Point the Go client at the StreamAlarms alarm feed

Regenerate the Go protobuf stubs and replace the session-scoped
QueryActiveAlarms surface with the session-less StreamAlarms feed:
snapshot-then-live AlarmFeedMessage fan-out served by the gateway's
central alarm monitor. Drops session_id from the acknowledge surface.
