Joseph Doherty 27a8d05b7c feat(driver-galaxy): consume the gateway's session-less alarm model ...

The mxaccessgw updated alarms to a session-less central monitor:
AcknowledgeAlarm dropped SessionId and alarm transitions now come from
the session-less StreamAlarms feed instead of the per-session worker
StreamEvents stream. The GalaxyDriver no longer compiled against the
updated client.

- GatewayGalaxyAlarmAcknowledger: session-less rewrite — no GalaxyMxSession;
  outcome read from ProtocolStatus (throw) and Hresult (warn).
- New IGalaxyAlarmFeed seam + GatewayGalaxyAlarmFeed: background consumer
  of StreamAlarms that decodes the active-alarm snapshot plus live
  transitions into GalaxyAlarmTransition and reopens the stream on
  transport faults.
- EventPump: drop the dead per-session OnAlarmTransition path; the
  per-session stream no longer carries alarms.
- GalaxyDriver: bridge the feed onto IAlarmSource.OnAlarmEvent; the feed
  starts on SubscribeAlarmsAsync, independent of data subscriptions.
- Tests: replace EventPumpAlarmTests with GatewayGalaxyAlarmFeedTests;
  move the driver alarm-source tests onto the IGalaxyAlarmFeed seam.

Browse needed no change — GatewayGalaxyHierarchySource consumes the
unchanged DiscoverHierarchy contract.
