feat(hosts): managed Hosts for per-host subscription link overrides (#5409)

* test(sub): characterize current link output (externalProxy + single-link baselines)

Phase 0 of the Hosts feature. Locks current subscription-link output for the
externalProxy paths (vless/vmess/trojan/ss exact, reality/hysteria by Contains)
so the upcoming ShareEndpoint refactor can be proven behavior-preserving. These
must stay green and unedited through every later phase.

* refactor(sub): unify external-proxy link building behind ShareEndpoint (TDD, snapshot-locked)

Phase 1 of the Hosts feature. Collapse the duplicated externalProxy link
builders (param-form for vless/trojan/ss, object-form for vmess) onto a single
ShareEndpoint abstraction so Phase 4 can add Host-driven links with ~zero new
branching.

Design: an externalProxy-derived endpoint carries the original entry map and
applies it through the UNCHANGED applyExternalProxyTLS{Params,Obj} helpers, so
output is provably byte-identical. buildExternalProxyURLLinks /
buildVmessExternalProxyLinks become thin adapters; the genVless/Trojan/SS/Vmess
call sites are untouched. genHysteriaLink is deliberately left on its own path
(hex pinSHA256, not pcs). The no-externalProxy default tails are unchanged.

TDD: N1-N4 (externalProxyToEndpoint, inboundDefaultEndpoint, buildEndpointLinks,
buildEndpointVmessLinks) written failing-first against stubs, then implemented.

Mutation sanity (performed + reverted): dropping the ep-carry in
externalProxyToEndpoint makes the Phase-0 C1/C2 characterization snapshots go
red (TLS overrides vanish), proving the snapshots guard the emitted output.

Gate: go test ./internal/sub/... and go test ./... green with ZERO edits to the
Phase-0 snapshots; go build ./... green on linux and windows; go vet clean.

* feat(model): Host entity + automigrate + openapi codegen (TDD)

Phase 2 of the Hosts feature. Adds the Host GORM model: an override endpoint
attached to an inbound (address/port + TLS/transport/clash overrides + sub
scoping), superseding the legacy externalProxy array functionally while leaving
it intact.

- model.Host with snake_case column tags, json serializer for slices, text for
  free-JSON (mux/sockopt/xhttp), validate tags (remark 1-40, port 0-65535,
  security + mihomoIpVersion enums); TableName "hosts". NodeGuids column is added
  now but unused (host->node scoping deferred to v2).
- Registered in BOTH initModels() (db.go) and migrationModels() (migrate_data.go);
  the latter is required for cross-DB migration and is easy to miss. PG sequence
  resync iterates the initModels slice, so it is covered automatically.
- pruneOrphanedHosts() deletes hosts whose inbound_id has no inbound, called
  alongside pruneOrphanedClientInbounds().
- openapigen manifest: Host added to StructAllow with MuxParams/SockoptParams/
  XhttpExtraParams -> KindAny; regenerated frontend/src/generated/* + openapi.json.

TDD: TestHostTableName, TestHostValidation, TestHostAutoMigrateCreatesColumns
(+ _Postgres), TestPruneOrphanedHosts written failing-first against a wrong-name,
untagged, unregistered stub, then implemented.

Gate: go test ./... green on SQLite AND a real Postgres DSN (local container);
go build/vet/gofmt clean; npm run gen succeeds with the new Host type/schema/
example/zod; npm run typecheck + npm run test (542) green.

* feat(api): Host CRUD service + controller + routes (TDD)

Phase 3 of the Hosts feature.

- service/host.go (HostService, empty struct + database.GetDB() like
  ClientService): GetHosts, GetHostsByInbound, GetHost, AddHost (verifies the
  inbound exists — no hard FK), UpdateHost (inbound + sort order immutable here),
  DeleteHost, SetHostEnable, SetHostsEnable, DeleteHosts, ReorderHosts (single
  driver-safe transaction), GetAllTags.
- controller/host.go mirrors NodeController: routes under /panel/api/hosts
  (list/get/byInbound/tags + add/update/del/setEnable/reorder + bulk/setEnable,
  bulk/del), binds via middleware.BindAndValidate so the model validate tags are
  enforced, {success,msg,obj} envelopes.
- Wired the hosts group into api.go after nodes (inherits checkAPIAuth + CSRF).
- DelInbound now cascades: deleting an inbound deletes its hosts.
- Documented all 11 routes in api-docs endpoints.ts (referencing the generated
  Host schema) and regenerated openapi.json; extended TestAPIRoutesDocumented's
  controller->basePath switch for host.go. Backend en toast keys added.

TDD: service tests (Add/GetByInbound, RejectsUnknownInbound, Reorder, Set/Bulk
enable, DeleteHosts, DeleteInboundCascadesHosts, GetAllTags) written failing-
first against a nil-returning stub; controller test (AddListGetDelete envelope
round-trip + AuthInherited 401) added.

Gate: go test ./internal/web/... + go test ./... green; npm run gen + typecheck
+ lint + test (542) + build green.

* feat(sub): render subscription links from hosts; legacy fallback when none (TDD, mutation-checked)

Phase 4 of the Hosts feature. Inserts host resolution between inbound and link
across all three subscription formats.

Mechanism: hostEndpoints(inbound, format) loads the inbound's enabled hosts
(filtered by ExcludeFromSubTypes, ordered by sort_order then id) and projects
each onto the externalProxy entry shape the raw/json/clash renderers already
consume. So a host fans out one link/proxy reusing the exact existing rendering
(address/port/security/sni/fp/alpn/pins/ech) with zero new TLS code. Host header
and path overrides are applied additively in the raw builders (no-op for legacy
externalProxy, which never carries those keys — characterization snapshots stay
green). Clash ip-version (MihomoIpVersion) is set last on the proxy.

Integration points:
- getSubs (raw): per inbound, hostEndpoints AFTER projectThroughFallbackMaster;
  len>0 -> linkFromHosts (renders only the hosts), else legacy GetLink.
- GetJson/GetClash: inject the host endpoints into the inbound's externalProxy
  before the existing getConfig/getProxies loop.
- Precedence: hosts win over any legacy externalProxy (injection replaces it).

Backward compat: a zero-host inbound takes the legacy path -> byte-identical
output (all Phase-0 characterization snapshots unchanged).

TDD: 9 cycles (zero-hosts identical, N-links-ordered with host/path override,
disabled skipped, host-vs-externalProxy precedence, no-dedup, sort composes with
SubSortIndex, host-over-fallback, resolve-via-client-inbounds, ExcludeFromSubTypes
per format) written failing-first against unwired helpers, then wired green.

Mutation sanity (performed + reverted, documented here):
- zero-hosts fallback: flipping the len(hostEps)>0 guard to >=0 makes
  TestSub_ZeroHosts_IdenticalOutput go red (host path yields "" for no hosts).
- no-dedup: adding a remark-dedup in hostEndpoints makes TestSub_NHosts_NoDedup
  go red (two distinct hosts collapse to one link).

Gate: go test ./internal/sub/... + go test ./... green with ZERO edits to the
Phase-0 snapshots; go build green on linux and windows; go vet + gofmt clean.

* feat(migration): seed hosts from inbound externalProxy (TDD, idempotent, dual-driver)

Phase 5 of the Hosts feature. One-time migration so existing installs surface
their legacy externalProxy entries as first-class Host rows.

- seedHostsFromExternalProxy() is self-gated on a HistoryOfSeeders
  "HostsFromExternalProxy" row (run-once) and wired into runSeeders. For each
  inbound it parses StreamSettings, reads externalProxy[], and creates one Host
  per entry: forceTls->Security (unknown->same), dest->Address, port->Port,
  remark->Remark (generated when blank, capped at 40), sni/fingerprint/alpn/
  pinnedPeerCertSha256/echConfigList copied; SortOrder=index; InboundId set.
- Additive: externalProxy is left intact in StreamSettings (rollback-safe; the
  sub layer prefers hosts when present, §Phase 4).
- Postgres: GORM db.Create advances hosts_id_seq via the sequence, so no extra
  resync is needed beyond the existing startup resync.

TDD: field-mapping, idempotency (second run no-op), no-externalProxy->no-hosts,
externalProxy-kept-intact written failing-first against a stub; plus a
Postgres counterpart that skips without XUI_DB_DSN.

Gate: go test ./internal/web/service/... ./internal/database/... green on SQLite;
the *_Postgres tests green against a real Postgres container; go build green on
linux and windows; go vet + gofmt clean. (Running the whole database package
under XUI_DB_TYPE=postgres is not supported — the SQLite-path tests share the one
DSN — so only the t.Skip-gated *_Postgres tests run with the env set.)

* feat(ui): Hosts page + schema + query hooks + link preview helper (TDD on schema/helpers)

Phase 6 of the Hosts feature — the admin UI.

- schemas/api/host.ts: HostFormSchema (validation: remark 1-40, tags ^[A-Z0-9_:]+$
  ≤10×≤36, port 0-65535, security/mihomoIpVersion enums, alpn/fingerprint reused
  from the shared primitives) + a loose HostRecordSchema/HostListSchema for reads.
- lib/hosts/host-link.ts: hostToExternalProxyEntry — the frontend mirror of the
  backend hostToExternalProxyMap (security->forceTls, sni override rules, port
  inherit), for share-link previews.
- api/queries/useHostsQuery.ts + useHostMutations.ts (mirror the node hooks):
  list/get + add/update/del/setEnable/reorder/bulk; queryKeys.hosts.* added;
  mutations invalidate keys.hosts.root().
- pages/hosts/{HostsPage,HostList,HostFormModal}.tsx (+CSS) mirroring pages/nodes:
  list with remark · address:port · inbound · security · tags · enable Switch ·
  per-inbound move up/down (reorder) · bulk enable/disable/delete; form grouped
  into Basic / Advanced / Clash / Subscription-scope sections.
- Route '/hosts' + sidebar item (Global icon); menu.hosts + pages.hosts.* added to
  the en-US bundle (other locales fall back to English until translated).

TDD: HostFormSchema (10 cases) and hostToExternalProxyEntry (6 cases) written
failing-first, then implemented. UI verified by lint/typecheck/test/build.

Deferred (documented enhancement): the live in-form share-link preview (needs
inbound+client context) and a per-host host/path override in JSON/Clash output
(raw already overrides; JSON/Clash inherit the inbound's host/path).

Gate: cd frontend && npm run lint && npm run typecheck && npm run test (557) &&
npm run build all green; go build ./... + go test ./... still green.

* refactor(ui): remove the External Proxy form from the inbound stream settings

Hosts supersede the legacy externalProxy: the subscription renders from hosts
(hosts win when both exist) and the migration converts existing externalProxy
entries to hosts. externalProxy's only real consumers were the subscription
(now covered) and this form's preview — the backend per-client copy-link never
used it — so removing the editor has no functional regression.

- Drop ExternalProxyForm + toggleExternalProxy from InboundFormModal and delete
  the orphaned form component + its export; remove its block test + snapshot.
- KEEP the externalProxy schema field and backend parsing/link-generation: an
  existing inbound's externalProxy still round-trips through the form (not
  silently destroyed on edit) and still renders if a host was removed.

Gate: cd frontend && npm run typecheck + lint + test (556) + build green.

* fix(ui): use Alert `title` instead of deprecated `message` (antd 6)

Ant Design 6 deprecated <Alert message=> in favor of <Alert title=>; the panel
was mid-migration (21 Alerts already on title). Renamed the 7 remaining stragglers
across 5 files (SubLinksModal, InboundFormModal, sockopt, EmailTab, TelegramTab),
silencing the runtime deprecation warning. description= is unchanged.

Pre-existing warning, surfaced while testing Hosts — not introduced by it.

Gate: npm run typecheck + lint + test (556) + build green.

* style(ui): align Hosts page with Clients/Inbounds cards + reorder columns

- page-shell.css never listed .hosts-page, so the Hosts page got no content
  padding / transparent-layout / summary-card spacing. Add a .hosts-page shell
  block (background, dark/ultra vars, content-area + summary-card padding). This
  is the actual "card spacing" bug.
- HostList: match the Clients/Inbounds list card — hoverable + the toolbar moved
  into the card title as a .card-toolbar (Add when nothing selected; selected
  count + bulk enable/disable/delete on selection). Re-declare .card-toolbar in
  HostList.css since the shared rule lives in a lazily-loaded page stylesheet.
- Reorder table columns as requested: Actions, Enable, then Remark, Endpoint,
  Inbound, Security, Tags. Added scroll x for narrow screens.
- HostsPage: add a summary card (Total / Enabled / Disabled) like the other
  pages. New i18n keys: pages.hosts.selectedCount + pages.hosts.summary.*.

Gate: npm run typecheck + lint + test (556) + build green.

* style(ui): use Tabs instead of Collapse in the Add/Edit Host form

The Basic / Advanced / Clash / Subscription-scope sections are now tabs. Each
pane sets forceRender so all fields stay mounted — required because the form
uses preserve=false, so an unmounted tab's values would otherwise be dropped on
submit (and a required field on a hidden tab still blocks submit).

Gate: npm run typecheck + lint + test (556) + build green.

* style(ui): split Host form into Security + Advanced tabs; drop unused JSON fields

- Remove the Mux/Sockopt/XHTTP raw-JSON fields from the Host form: they were not
  wired into link generation and the inbound's structured editors are inbound-
  specific (not reusable). The DB columns + read schema + generated type stay, so
  they can get proper editors later. (HostFormSchema drops them; HostRecordSchema
  keeps them.)
- Reorganize tabs to Basic / Security / Advanced / Clash / Subscription scope:
  Security holds the TLS/cert fields (security, sni, sni-overrides, alpn,
  fingerprint, pins, verify-by-name, ech); Advanced now holds the transport
  overrides (host header, path).
- i18n: add pages.hosts.sections.security; drop the 3 unused field labels.

Gate: npm run typecheck + lint + test (556) + build green.

* style(ui): restore Mux/Sockopt/XHTTP fields in the Host Advanced tab

Put the three free-JSON override fields back, in the Advanced tab next to host
header / path (as JSON inputs — the inbound's structured editors aren't reusable
here). Re-added to HostFormSchema + defaults + the i18n labels.

Gate: npm run typecheck + lint + test (556) + build green.

* feat(hosts): add allowInsecure (rendered) + serverDescription/mihomoX25519/vlessRouteId fields

Closes most of the Remnawave-host gap analysis.

- model.Host: + allowInsecure, serverDescription (≤64), vlessRouteId (0-65535),
  mihomoX25519. Auto-migrated (SQLite + Postgres verified); openapi regenerated.
- allowInsecure is fully RENDERED into subscription output (TDD):
  - raw link: allowInsecure=1 (TLS/Reality, skipped for none) via the endpoint
    builder;
  - JSON/Clash: applyExternalProxyTLSToStream writes tlsSettings.settings.
    allowInsecure, and clash applySecurity now emits skip-cert-verify for the tls
    case (it previously only did so for Hysteria — a pre-existing gap, so inbound
    allowInsecure now renders for vless/trojan/ss clash too).
- Frontend: the four fields added to the Host form (allowInsecure → Security,
  serverDescription → Basic, vlessRouteId → Advanced, mihomoX25519 → Clash);
  serverDescription shown under the remark in the list. Schema + i18n updated.

serverDescription / vlessRouteId / mihomoX25519 are stored + editable; their
deeper rendering (and per-host mux/sockopt/xhttp into JSON/Clash, plus a per-host
xray JSON template) are tracked as follow-ups.

Gate: go test ./... green (SQLite + Postgres for the host schema/migration);
go build linux+windows; go vet + gofmt clean; npm run gen + typecheck + lint +
test (556) + build green; generated files in sync.

* feat(sub): render host sockopt + xhttp-extra params into JSON/Clash output (TDD)

A host's sockoptParams and xhttpExtraParams (free-JSON) now take effect:
applyHostStreamOverrides injects sockopt into the per-host stream (re-added since
the base stream strips it) and merges xhttpExtraParams into xhttpSettings, called
in both getConfig (JSON) and getProxies (Clash) right after the per-host TLS
apply. No-op for legacy externalProxy entries (keys absent) — characterization
snapshots unchanged.

mux rendering is outbound-level (overrides outbound.Mux) and needs a genVless/
genVnext/genServer signature change — deferred, along with the per-host xray
JSON template.

Gate: go test ./internal/sub/... + go test ./... green (snapshots unchanged);
go build + vet + gofmt clean.

* feat(sub): render host muxParams as a per-host JSON outbound mux override (TDD)

genVnext/genVless/genServer take a muxOverride: a host's muxParams (when valid
JSON) overrides the global mux on its JSON outbound; empty falls back to the
panel mux (behavior unchanged for non-host configs). Completes the host
mux/sockopt/xhttp trio. Test call sites updated for the new signature.

Gate: go test ./internal/sub/... + go test ./... green (snapshots unchanged);
go build + gofmt clean.

* style(ui): show Host security fields conditionally per security (like externalProxy)

* feat(sub): apply host SNI + fingerprint override for reality (TDD)

A reality host now overrides SNI and fingerprint while inheriting publicKey/
shortId from the inbound (reality keys can't be host-supplied). Previously the
reality link kept the inbound's serverName because the TLS appliers are gated to
security=="tls".

- raw: applyEndpointRealityParams sets sni/fp on the params for reality;
- JSON/Clash: applyHostStreamOverrides sets realitySettings.serverName +
  serverNames from the host SNI.

Gated to host endpoints via an isHost marker on the synthesized ep, so the legacy
externalProxy path stays byte-identical (characterization snapshots unchanged).
The marker is internal and never emitted.

Gate: go test ./internal/sub/... + go test ./... green; go build + vet + gofmt clean.

* fix(ui): start the Host inbound select unselected instead of showing 0

A new host left inboundId defaulting to 0, so the Select rendered "0". inboundId
is now optional in the form (undefined until chosen), so it shows its
placeholder ("Select an inbound"); the required rule still enforces a choice on
save. Port keeps 0 (means "inherit the inbound's port").

Gate: npm run typecheck + lint + build green.

* fix(ui): drop redundant :port suffix from the Host inbound select label

The inbound tag (e.g. in-59303-tcp) already carries the port, so the appended
":59303" was duplicated. Show just the remark/tag.

Gate: npm run typecheck + lint + build green.

* style(ui): apply the shared card hover shadows to the Hosts page

page-cards.css scoped its card styling + hover shadows to each page class but
not .hosts-page, so Hosts fell back to antd's default hoverable (a larger/blurry
shadow + pointer cursor). Add a .hosts-page block matching the other pages.

Gate: npm run build green.

* feat(hosts): move Tags to Basic tab, add Nodes field, accept VLESS route ranges

- Move the Tags field into the Host form's Basic tab and add a Nodes
  multi-select (visual-only assignment, backed by the existing node_guids
  column) so the Basic tab matches the reference layout.
- Replace the single-port vlessRouteId integer with a free-form vlessRoute
  string that accepts comma-separated ports/ranges (e.g. 53,443,1000-2000);
  format-validated on the frontend, stored verbatim on the backend.
- Regenerated frontend types/openapi from the changed model.

* feat(hosts): structured editors for Mux/Sockopt/XHTTP + new Final Mask

Replace the raw JSON textareas in the Host form's Advanced tab with the same
structured editors used elsewhere, under a nested tabbed layout (General / Mux /
Sockopt / XHTTP / Final Mask), mirroring the Sub-JSON settings tab:

- Mux: the Sub-JSON mux editor (enable + concurrency/xudpConcurrency/xudp443).
- Sockopt + XHTTP: reuse the outbound SockoptForm / XhttpForm, wrapped in an
  isolated form that serializes the edited subtree back to the host's JSON
  string (pruned so the override stays sparse).
- Final Mask: new host field (model + column + JSON-render wiring that merges
  the masks into the host's JSON-subscription stream), edited via the shared
  FinalMaskForm like the Sub-JSON Final Mask editor.

Each editor stays a controlled value/onChange component bound to its existing
host JSON string field; backend rendering of mux/sockopt/xhttp is unchanged.

* feat(hosts): drop XHTTP + Xray-JSON-template overrides; fix mobile form layout

Remove the host's XHTTP extra-params and Xray-JSON-template overrides entirely
(model fields + columns, JSON-subscription render paths incl. hostTemplateOutbound,
schema, form tab/field, i18n, openapi codegen, and their tests) — they did not
fit the host model. Mux, Sockopt and Final Mask stay as structured editors.

Mobile fixes for the Edit Host modal:
- responsive width (95vw on mobile, was a fixed 760px that overflowed the
  viewport and clipped the tabs/labels) + a scrollable body so the footer stays
  on screen;
- Mux fields use responsive Row/Col (stack on mobile) instead of a fixed-width
  label grid.

* fix(hosts): hide the spurious horizontal scrollbar in the Edit Host modal

Setting overflowY:auto on the modal body forced overflow-x to auto too (CSS
rule), so antd Row's negative gutter margins triggered a horizontal scrollbar.
Pin overflowX:hidden.

* feat(hosts): inbound-style responsive field layout + icon empty state

- Host form (main form + Mux/Sockopt/Final Mask editors) now use the inbound
  form's label layout: label beside the input on desktop (labelCol sm span 8 /
  wrapperCol sm span 14, right-aligned), stacked label-above-input on mobile.
  Rewrote HostMuxForm onto an internal antd Form so it follows the same layout
  instead of a manual grid.
- Empty hosts table now shows the host icon + the shared 'Nothing here yet'
  (noData) text, matching Nodes/Inbounds/Clients, replacing the bespoke
  'No hosts yet…' string.

* fix(hosts): avoid nested <form> in the Edit Host modal

The Mux/Sockopt/Final Mask editors each render their own antd Form inside the
host's main Form, producing an invalid nested <form> DOM node (hydration
warning). Render those inner forms with component={false} so they keep the form
instance/context but emit no <form> element.

* fix(hosts): make the Mux enable toggle work

The Switch's checked state came from Form.useWatch('mux'), but the mux object
field had no registered Form.Item while disabled, so setFieldValue never
notified the watcher and the toggle stayed off. Bind the Switch to a real
name='enabled' field (antd drives its checked state directly) and keep the
sub-fields registered via hidden={!enabled}, serialized to the flat mux JSON.

* refactor(hosts): reuse the outbound MuxForm instead of a bespoke Mux editor

The Mux fields duplicated the outbound MuxForm. Reuse it through the same
wrapper as Sockopt: generalize OutboundSubtreeJsonForm with defaultSubtree
(pre-fill on enable) and a serialize hook, and have HostMuxForm render MuxForm
at the ['mux'] path. The host keeps its inherit-when-off semantics by storing ''
unless mux.enabled. Also drops the now-unused enableSwitch path from the
wrapper (only the removed XHTTP editor used it).

* style(hosts): use default-width Port input like the inbound form

The host Port used width:100% (full width); the inbound's numeric inputs use
antd's default width. Drop the override so Port matches. The Mux number inputs
already use the default width via the reused MuxForm.

* refactor(sockopt): readable customSockopt editor as a shared component

The customSockopt rows were a single cramped Space.Compact line and duplicated
verbatim in the inbound and outbound sockopt forms. Extract a shared
CustomSockoptList that renders each entry as a titled group of labeled fields
(System / Level / Opt / Type / Value), matching the rest of the form, and use it
in both (and thus the host Sockopt editor).

* fix(finalmask): drop the empty Custom Tables tag on a new sudoku mask

The sudoku TCP-mask default seeded customTables: [''] (one empty string), which
rendered as a blank removable tag. Seed [] instead.

* fix(sockopt): make the outbound (and host) Sockopt client-only

Per the XTLS sockopt docs, tproxy / acceptProxyProtocol / V6Only /
trustedXForwardedFor only apply to an inbound (listening socket); they are
meaningless on an outbound/dialer. Drop them from the outbound SockoptForm
(which the host reuses). The Sockopt default object still seeds those keys, so
the host also strips them on serialize, keeping its override honest to the
server/client split. The inbound SockoptForm is left unchanged.

* fix(sockopt): make the inbound Sockopt server-only

Complete the server/client split: drop the outbound/dialer-only fields from the
inbound SockoptForm — dialerProxy, domainStrategy, interface, addressPortStrategy,
happyEyeballs, tcpMptcp (client-only since Go 1.24 auto-enables MPTCP on listen).
mark stays (xray applies SO_MARK on inbound sockets too). Update the form-blocks
snapshot to the server-side field set (intentional spec change).

* feat(hosts): populate Sockopt dialerProxy with the panel's outbound tags

The host Sockopt editor reused the outbound SockoptForm with outboundTags=[],
so the dialerProxy dropdown was empty. Feed it the panel's outbound tags via
the existing useOutboundTags hook (shares the cached xray-config query;
blackhole excluded), so a host can chain through a subscription outbound by tag.

* fix(hosts): empty-state styling on direct load + exclude balancers from dialerProxy

- .card-empty was only defined in lazily-loaded Clients/Inbounds/Nodes
  stylesheets, so a direct /hosts refresh rendered the empty table state
  unstyled (faint + uncentered) until another page was visited. Re-declare it
  in HostList.css so it's correct on first load.
- The Sockopt dialerProxy dropdown listed balancer tags (useOutboundTags merges
  them in for mtproto egress). dialerProxy chains a single outbound, so balancers
  aren't valid — switch to useOutboundTagGroups and use only the outbound group.

* fix(outbounds): icon + 'Nothing here yet' empty state; stop fading other pages

The Outbounds empty state was a faint '—', and OutboundsTab.css set the global
.card-empty to opacity:0.4 — which leaked onto whichever page's empty state was
shown after the Outbounds CSS had loaded (e.g. Hosts went faint after visiting
Outbounds). Render the icon + noData ('Nothing here yet') like the other lists,
and align .card-empty to the shared centered/secondary style (no opacity).

* fix(outbounds): custom empty state on the desktop table too

The desktop Outbounds Table had no locale.emptyText, so it showed antd's
default 'No data' box. Add the same ExportOutlined + noData empty state as the
card (mobile) view.

* style(sidebar): use ExportOutlined for the Outbounds nav item

The Outbounds sidebar item used UploadOutlined (an upload tray). Switch to
ExportOutlined, matching the outbound icon now used in the routing target and
the outbounds empty states.

* feat(hosts): icons on the form tabs (icon-only on mobile)

Wrap every Host form tab label (Basic/Security/Advanced/Clash/Subscription
scope and the nested General/Mux/Sockopt/Final Mask) with catTabLabel, so the
tabs show icon + text on desktop and just the icon (with a tooltip) on mobile,
matching the Settings/Xray tab bars.

* refactor(hosts): fold Exclude-from-formats into Advanced, drop the one-field tab

The Subscription scope tab held only excludeFromSubTypes after Tags moved to
Basic — a niche per-format scoping knob. Move it into the Advanced > General
sub-tab and remove the standalone tab (and its now-unused subScope label/icon).

* feat(sub): per-client remark template variables; drop the remark model & Show Usage Info

* fix(migration): cap seeded host remark at the model's 256-char limit, not 40
