AlarmActor (computed) and NativeAlarmActor (native mirror) now fire-and-forget an 'alarm' site operational event on every state transition: - raise/activate: Error (priority/severity >= 700) or Warning - clear/return-to-normal, ack, inter-band transition: Info Both actors take a new optional IServiceProvider? ctor param (default null so existing direct-construction tests still compile); InstanceActor passes its _serviceProvider at the two Props.Create sites. Resolution is optional and the LogEventAsync call is fire-and-forget, so a logging failure never affects alarm evaluation. Rehydration replays are not re-logged. Adds a capturing FakeSiteEventLogger test helper + SingleServiceProvider.
