* fix(clients): keep a vless reverse client's handler across a re-add
RemoveUser also drops the client's reverse outbound handler, and the account
every live remove/re-add path rebuilt carried no reverse at all: buildUserAccount
read id/flow/testseed/testpre and nothing else. Editing, bulk re-enabling, quota
renewal and adding a client to an existing inbound therefore left a reverse
client able to connect but not to open its tunnel until Xray restarted, with
nothing logged. A traffic reset is the route operators hit most, since a
depleted client is removed and re-added on every renewal.
buildUserAccount now carries the tag (it accepts either the settings JSON object
or a typed client value), and the five account maps those paths build include
the client's reverse. Core chain, read from the pinned xray-core:
AddUserOperation -> User.ToMemoryUser -> vless.Account.AsAccount copies Reverse
(proxy/vless/account.go:24), and GetReverse rebuilds the handler from the stored
account's tag (proxy/vless/inbound/inbound.go:193-205).
Each path has a test that fails without its fix; the account-level test fails on
both input shapes.
* refactor(clients): drop an account map helper nothing calls
Local.AddClient and Local.UpdateUser are only reachable through runtime.Runtime,
and all four call sites of those two methods sit in a node branch, where the
runtime is a *Remote -- Remote.AddUser ignores the map and pushes the inbound
snapshot instead. So the extraction and its test covered a path no deployment
takes, the reverse key it added could never reach a core, and the previous
commit's claim that the node-push paths go through it was wrong.
The four account maps that do reach buildUserAccount are untouched. Reported by
the PR review.
