feat(web): broadcast delta client stats above a snapshot threshold

Browse Source 
Both 5s broadcasters (the local traffic poll and the node traffic sync)
shipped the complete client_traffics table on every cycle while a browser
was connected. At 500k clients that is a 1.7s full-table read plus an
86MB marshal per job per poll — and the hub drops any payload over 10MB
and sends an invalidate the frontend ignores for these message types, so
past ~55k clients all of it was pure waste and the UI got nothing.

Installs at or below 5000 clients (clientStatsSnapshotMaxClients) keep
the exact full-snapshot behavior — it exists because a pure delta feed
left UI rows stale when nothing moved in a cycle (see GetAllClientTraffics)
— and the payload now carries snapshot=true. Above the threshold the jobs
send only this cycle's active rows (the xray poll's active emails, or the
emails online on the synced nodes) with snapshot=false, and scope the
last-online map to those rows; the initial full map still arrives over
REST and the clients page refetches every 5s.

GetActiveClientTraffics gains the overlayGlobalTraffic pass so delta rows
carry the same cross-panel usage as snapshot rows. The node job also
stops reading the full last-online map before the has-clients gate, which
was a wasted full-table read on every tick with no dashboard open.

Frontend: useClients keeps its live summary strictly snapshot-driven
(snapshot=false payloads skip the allClientStats replace and the summary
falls back to the server-computed one); the per-row page merge and the
inbounds-page merges already handle deltas.
