The gateway now monitors alarms continuously, independent of any client session, and fans the feed out to every client. GatewayAlarmMonitor is an always-on hosted service that owns one gateway-managed worker session dedicated to alarms: it subscribes the configured provider, caches the active-alarm set from the worker's transition events (reconciled periodically against the worker's authoritative snapshot), re-opens the session if the worker faults, and broadcasts to all subscribers. The new session-less StreamAlarms RPC opens with the current active-alarm snapshot, then streams live transitions; any number of clients fan out from the single monitor without opening a worker session. AcknowledgeAlarm is now session-less and routes through the monitor. The session-scoped QueryActiveAlarms RPC and the per-session alarm auto-subscribe hook are removed, along with the now-dead IAlarmRpcDispatcher trio; the dashboard Alarms tab reads the monitor's in-process cache directly. This intentionally reverses the v1 "no multi-subscriber fan-out" decision for the alarm subsystem. Contracts regenerated; gateway, dashboard and tests build clean, 94 alarm-affected tests pass, and the monitor is verified live. Language-client stubs are regenerated in a follow-up change.
