fix(inbounds): refresh client rows live over websocket

Two bugs combined to leave per-client traffic / remained / all-time
columns stuck at stale numbers while only the inbound-level row and
the online badge refreshed:

1. Backend (xray + node sync traffic jobs) only included the per-client
   array in the client_stats broadcast when activeEmails / touched
   was non-empty. Cycles with no client deltas — or any node sync that
   failed to fetch a snapshot — shipped only the inbound summary, so
   the frontend had nothing to merge for clients. Replaced both code
   paths with a single GetAllClientTraffics() snapshot per cycle; the
   broadcast now always carries the full client list.

2. Frontend mutated dbInbound.clientStats[i] in place. DBInbound is a
   plain class instance (not wrapped in reactive()), so Vue could not
   see the field-level changes and ClientRowTable's statsMap computed
   stayed cached forever. Added a statsVersion tick bumped on every
   merge and read inside statsMap so the computed re-evaluates and the
   template pulls fresh up/down/allTime/expiryTime each push.

Removed the now-dead emailSet helper from node_traffic_sync_job and
the activeEmails filter from xray_traffic_job.
