Kuzz007 71dc453970 feat(amneziawg): make the Xray TPROXY bridge a per-inbound opt-in
Addresses Finding 10 from the automated PR review: an always-on TPROXY
bridge makes every AmneziaWG tunnel hard-depend on Xray being up (all
traffic, including DNS, drops whenever Xray restarts), and forces a full
awg-quick down+up bounce on any client add/remove/re-IP, permanently
losing the syncconf fast path.

Adds ServerSettings.RouteThroughXray (off by default):

- defaultPostUpDown only emits the TPROXY/policy-route rules when it's
  on; a plain AmneziaWG tunnel now has zero Xray dependency out of the
  box.
- structuralFingerprint covers it (toggling it changes whether PostUp/
  PostDown contain any TPROXY rules at all -- structural, not a
  per-peer host-rule). hostRulesFingerprint's IPv4 tracking is now
  itself conditional on RouteThroughXray (and IPv6 tracking on
  IPv6Enabled), so an instance that never uses either keeps the
  syncconf fast path for a plain peer re-IP.
- injectAmneziawgEgress only creates a bridge for inbounds that opted
  in; checkAmneziawgEgressConflict (the Finding-7 fix) now parses each
  candidate through InstanceFromInbound so a non-routed inbound's port
  is correctly never treated as reserved.
- New inbound-level Switch in the AmneziaWG form; the actual outbound
  decision is still made entirely through the panel's stock Routing
  page, same as before -- only whether the bridge exists at all is now
  a choice.

Translation keys added to all 13 locales in the same commit this time,
not backfilled later (see Finding 9's lesson).

Kuzz007 db8253421a refactor(amneziawg): route via Xray through the stock Routing page, not custom toggles
Simplifies RouteViaXray after realizing the panel already has everything
needed: the Routing page already lets an admin pick a source inbound tag
and a target outbound (plus, if they want it, a specific source IP) for
any protocol. Bolting a parallel routeThroughXray/routeOutboundTag pair
onto both the client and inbound forms duplicated that mechanism instead
of using it.

Removed entirely: Client/ClientRecord/ServerSettings/Peer's
RouteThroughXray + RouteOutboundTag fields, the effective-routing OR/
fallback logic in InstanceFromInbound, and the Switch+Select UI on both
forms. Nothing configures "route via Xray" as a setting anymore.

In its place, every enabled AmneziaWG inbound now gets its own Xray
TPROXY bridge unconditionally, by default, no toggle:

- internal/amneziawg: every peer's traffic is always TPROXY'd into that
  instance's own bridge (defaultPostUpDown, port derived from the
  inbound's id via EgressPortForInbound so the kernel side and the
  Xray-config side never need to negotiate a runtime value). Since the
  TPROXY rule is now tied to a peer's mere presence rather than an
  opt-in flag, hostRulesFingerprint now covers every peer unconditionally
  (add/remove/re-IP forces a restart, the same way ForwardedPorts always
  did) instead of skipping peers with nothing to opt into.
- internal/web/service/xray.go's injectAmneziawgEgress creates one
  dokodemo-door bridge per qualifying inbound, tagged with that inbound's
  own real tag — the same trick injectMtprotoEgress already uses (reusing
  a real inbound's tag), which is why it's already selectable in the
  panel's Routing page: InboundService.GetInboundTags() is a plain,
  protocol-blind SELECT over every inbound row's tag, no dedicated UI
  plumbing needed. The function never generates a routing rule itself
  anymore — where (if anywhere) that traffic goes is entirely up to
  whatever rules the admin adds through the existing Routing UI.

Frontend: no new UI at all. Tests rewritten to match — one bridge per
inbound with its own tag/port, no rule generation, no opt-in gating.

Kuzz007 909feefd1d fix(amneziawg): make RouteViaXray an inbound-level option too
RouteThroughXray/RouteOutboundTag were client-only, but the more common
case is "route this whole AmneziaWG server's traffic through Xray", not
configuring every peer individually. Add the same pair to ServerSettings
(inbound-level) while keeping the per-client fields as an override —
matching how ExternalInterface/IPv6Enabled already work at the server
level next to per-client settings like ForwardedPorts.

Effective per-peer decision (computed once, in InstanceFromInbound, not
duplicated at each consumer):
  - routed = client.RouteThroughXray || server.RouteThroughXray
  - outbound tag = client's own if set, else the server's default

This means a peer can be routed by the inbound-wide default with no
config of its own, opt in on its own even when the default is off, or
keep the default's on/off but pick a different outbound than everyone
else.

internal/web/service/xray.go's injectAmneziawgEgress now calls
amneziawg.InstanceFromInbound instead of re-parsing InboundSettings and
reading model.Client fields directly — the same effective-routing
computation the kernel-side TPROXY rules use, so the two independent
reconcile loops (Xray-config generation and the AWG manager) can never
quietly disagree about which peers are actually routed.

Frontend: Switch + conditional outbound Select added to the AWG inbound
form (mirroring the client-form version and mtproto's own UI), plus the
inbound-defaults.ts default-object fix that's bitten this project's CI
before (Phase 2a) whenever ServerSettings gains a new required-shaped
field.

Test fixtures in xray_config_inject_test.go needed a real Server block
and PublicKey once injectAmneziawgEgress started requiring a usable
InstanceFromInbound result — both were implicit fixture gaps, not
behavior the old tests were actually asserting.

Kuzz007 d1b77b2aa4 feat(amneziawg): Phase 2c — RouteViaXray (TPROXY into Xray)
Per-client toggle (RouteThroughXray + RouteOutboundTag) that TPROXYs a
peer's traffic into Xray instead of NAT'ing it straight out the host's
network interface, so it can egress through any configured Xray
outbound (or balancer) — a VLESS/proxy chain, WARP, etc.

Discovered mid-design that internal/mtproto already solved the "let a
native sidecar's traffic egress through Xray" problem once, via
routeThroughXray/routeXrayPort/outboundTag + injectMtprotoEgress: a
loopback bridge inbound plus a routing rule. AmneziaWG can't reuse it
directly — mtg is a userspace process that dials *out* through a local
SOCKS proxy, while AmneziaWG is a kernel tunnel interface with no
process of its own to redirect. The Xray-side shape carries over
almost exactly, the kernel-side plumbing is new:

- internal/amneziawg/route_egress.go: EgressPort/EgressTag/EgressFwmark/
  EgressTable are one shared constant set, not one bridge per peer.
  Every routed peer, across every AmneziaWG instance, TPROXYs into the
  *same* loopback dokodemo-door bridge; the per-peer distinction happens
  downstream, in Xray's own router, matched against each peer's
  TPROXY-preserved source IP (Xray's field-rule `source` matcher — a
  capability the router already had). This avoids two independent
  reconcile loops (the AWG manager and the Xray-config generator) ever
  having to agree on a dynamically-picked port for each peer.
- manager.go's defaultPostUpDown emits a per-peer mangle-table TPROXY
  rule (matched by tunnel source IP) for each opted-in peer, plus the
  fwmark->table->local-everywhere policy route TPROXY needs to deliver
  those packets to the bridge. That policy route is system-wide, not
  interface-specific, so — like the existing IPv6-forwarding sysctl —
  it's added idempotently and never torn down in PostDown; a second
  AmneziaWG instance with its own routed peers must find it already in
  place, not race to remove what the first still needs.
- The existing portForwardFingerprint became hostRulesFingerprint,
  covering both ForwardedPorts and RouteThroughXray/RouteOutboundTag:
  both only ever take effect through PostUp/PostDown, which `awg
  syncconf` never re-runs, so either one changing must force the same
  full interface bounce.
- internal/web/service/xray.go's new injectAmneziawgEgress mirrors
  injectMtprotoEgress/injectPanelEgress's safety rules, adapted for one
  bridge serving many peers: an invalid or missing outbound target
  skips only that one peer's rule (not the whole bridge, since other
  peers may still need it), while the bridge itself is skipped
  entirely when nothing needs it or its tag is already taken by a real
  inbound.

Frontend: a Switch + conditional outbound Select on the client form
(showAmneziawg only), mirroring mtproto's own routeThroughXray UI and
reusing its useOutboundTags hook. install.sh now modprobes the
mainline TPROXY modules (xt_TPROXY, nf_tproxy_ipv4/ipv6) alongside the
existing AmneziaWG setup — ordinary upstream kernel modules, no
DKMS/PPA needed unlike the AmneziaWG module itself.

Kuzz007 69de904bf6 feat(amneziawg): Phase 2b — per-client port-forwarding
Admins can now set a per-client ForwardedPorts string (e.g. "80, 443,
8000-8100") that gets DNAT'd + FORWARD'd to that peer's tunnel address
via iptables rules in PostUp/PostDown, ported and simplified from
coinman-dev/3ax-ui's shared/portfwd.

Two decisions worth flagging for future readers:

- The iptables --comment tag on each rule is awg-fwd-<fnv32a(email)>,
  not the raw client email. Email is admin/API-supplied free text that
  ends up embedded in a shell-executed PostUp/PostDown line; a hash
  can never carry a shell metacharacter through where raw
  interpolation could.
- The reconcile manager gained a third fingerprint (portFwdFP, next to
  the existing structural/peers ones). `awg syncconf` only touches the
  WireGuard peer table — it never re-applies PostUp/PostDown iptables
  rules — so a port-forward-only change has to force a full
  awg-quick down+up bounce, same as a structural change, rather than
  the lighter sync a plain peer add/remove can use.

Also fixes a real pre-existing bug found while wiring up IPv6 client
allocation in the previous commit's spirit: allocateWireguardAddress
always suffixed "/32" regardless of address family, which produced
invalid host bits for IPv6 (needs "/128").

ForwardedPorts flows through model.Client -> model.ClientRecord
(gorm column wg_forwarded_ports, auto-migrated) -> ToRecord/ToClient/
MergeClientRecord, mirroring the awgServer field's earlier lesson
that new fields need checking against a second, hand-maintained
persistence-layer struct.

Kuzz007 ef13e8567e feat(amneziawg): Phase 2a — IPv6 support + NDP proxy
Adds native dual-stack IPv6 to AmneziaWG inbounds, ported from
coinman-dev/3ax-ui's approach:

- ServerSettings gets ipv6Enabled/ipv6Subnet/ipv6ExternalInterface;
  Instance carries the server's own IPv6 address (first host of the
  subnet) alongside its IPv4 one.
- defaultAmneziaWGClients allocates an IPv6 host address per client
  (second AllowedIPs entry) when the server has IPv6 enabled, reusing
  allocateWireguardAddress — which needed a real fix along the way: it
  always suffixed "/32" regardless of address family, which is wrong
  for an IPv6 host address (needs /128). Now family-aware.
- generateServerConfig's PostUp/PostDown gains IPv6 forward-accept
  rules, proxy_ndp sysctl, and one `ip -6 neigh add/del proxy` entry per
  enabled peer with an IPv6 address — the lightweight per-client
  method, not the ndppd-daemon whole-subnet method (not worth the
  config-file-management complexity at this scale; ndppd itself is
  still installed by install.sh in case that changes later).
- ValidateIPv6Subnet rejects a malformed subnet before save.
- Frontend: ipv6Enabled/ipv6Subnet/ipv6ExternalInterface fields on the
  AmneziaWG inbound form, EN+RU translations, openapi.json/generated/*
  regenerated (the latter via `go run ./tools/openapigen`, pure Go).

Kuzz007 19082fdfe9 feat(amneziawg): add frontend support and fix a Go->Zod generator gap
Wires the amneziawg protocol through the panel UI the same way every
other protocol is registered: a Zod settings schema (nested
{server, clients}, matching the Go JSON exactly), the protocol enum,
the inbound-form's per-protocol fields component and its
tab-visibility allowlist, the default-settings factory, the client
schema dispatcher, and the sniffing-capability exclusion (no Xray
inbound exists for amneziawg, same as mtproto).

Client key/allowedIPs fields are reused rather than duplicated: since
AmneziaWG clients are wire-identical to WireGuard clients (same
model.Client fields), ClientFormModal renders one shared field block
for both, switching only the visible label by which protocol is
active. The private-key input also gets a live public-key sync via a
new useEffect, because unlike WireGuard's Xray-native inbound (which
re-derives its public key at runtime and never stores one),
AmneziaWG's server.publicKey is a real persisted field the Go backend
reads directly — free-typing a new private key without this would
silently save a mismatched keypair.

Adds a downloadable per-client .conf (amneziawgConfig.ts, mirroring
wireguardConfig.ts) with the obfuscation lines, and an
InboundOption.AwgServer field on the Go side so the config builder
gets the full server block in one round trip.

Along the way, running tools/openapigen surfaced a real bug: it
doesn't flatten anonymously-embedded Go structs the way encoding/json
does, so ServerSettings embedding Obfuscation20 produced a Zod schema
with a nested `obfuscation20` key that never matches the real wire
JSON. Fixed by un-embedding (flat fields + an accessor method) and
registering internal/amneziawg in the generator's own package list,
which had been silently emitting a dangling schema reference.

English and Russian translations are complete; the other 10 locale
files still fall back to English for the new keys.

Kuzz007 83cc545953 feat(amneziawg): add native AmneziaWG protocol backend
AmneziaWG (WireGuard plus DPI-resistant obfuscation) needs no Docker
here — it runs as a genuine kernel interface via awg-quick/awg, managed
the same way internal/mtproto manages mtg: one Inbound row is one
desired Instance, and a Manager reconciles running interfaces toward
the database every 10s (internal/web/job/amneziawg_job.go) plus
immediately after a client edit (applyLocalAmneziaWG).

Clients reuse model.Client verbatim (the same PrivateKey/PublicKey/
PreSharedKey/AllowedIPs fields WireGuard already uses), so bulk
operations, the QR/share-link modal and subscriptions come from the
shared inbound infrastructure instead of a parallel implementation.
internal/amneziawg owns the obfuscation param generator/validator
(ported from coinman-dev/3ax-ui, upgraded to AmneziaWG 2.0's S3/S4
padding and I1 signature packet) and the exec wrapper around
awg-quick/awg, with fingerprint-based reconcile (noop / reload-via-
syncconf / full restart) mirroring mtproto.Manager so a same-protocol
edit doesn't force an unnecessary interface bounce that would drop
every peer's connection.

Frontend and install.sh's DKMS/awg-tools setup are tracked separately;
this is backend-only.
