ws/inbounds: realtime fixes + perf for 10k+ client inbounds (#4123)HEADmain

* ws/inbounds: realtime fixes + perf for 10k+ client inbounds

- hub: dedup, throttle, panic-restart, deadlock fix, race tests
- client: backoff cap + slow-retry instead of giving up
- broadcast: delta-only payload, count-based invalidate fallback
- filter: fix empty online list (Inbound has no .id, use dbInbound.toInbound)
- perf: O(N²)→O(N) traffic merge, bulk delete, /setEnable endpoint
- traffic: monotonic all_time + UI clamp + propagate in delta handler
- session: persist on update/logout (fixes logout-after-password-change)
- ui: protocol tags flex, traffic bar normalize

* Remove hub_test.go file

* fix: ws hub, inbound service, and frontend correctness

- propagate DelInbound error on disable path in SetInboundEnable
- skip empty emails in updateClientTraffics to avoid constraint violations
- use consistent IN ? clause, drop redundant ErrRecordNotFound guards
- Hub.Unregister: direct removeClient fallback when channel is full
- applyClientStatsDelta: O(1) email lookup via per-inbound Map cache
- WS payload size check: Blob.size instead of .length for real byte count

* fix: chunk large IN ? queries and fix IPv6 same-origin check

* fix: chunk large IN ? queries and fix IPv6 same-origin check

* fix: unify clientStats cache, throttle clarity, hub constants

* fix(ui): align traffic/expiry cell columns across all rows

* style(ui): redesign outbounds table for visual consistency

* style(ui): redesign routing table for visual consistency

* fix:

* fix:

* fix:

* fix:

* fix:

* fix: font

* refactor: simplify outbound tone functions for consistency and maintainability
