Add two additive init-only fields to AlarmStateChanged so the Debug View can
nest live native conditions under their configured source-binding node:
- NativeSourceCanonicalName (binding canonical name, e.g. "Motor1.MotorAlarms")
- IsConfiguredPlaceholder (quiet-binding placeholder flag; default false)
Flow on BOTH cross-process paths:
- Live: proto AlarmStateUpdate fields 22/23 -> StreamRelayActor packs ->
SiteStreamGrpcClient unpacks (regenerated SiteStreamGrpc/Sitestream.cs).
- Snapshot (Newtonsoft): record defaults carry through; no special handling.
NativeAlarmActor.Emit now stamps NativeSourceCanonicalName = _source.CanonicalName.
Additive-only: no existing positional constructor or wire frame changed.
Tests: StreamRelayActorTests round-trips both fields pack->unpack;
NativeAlarmActorTests asserts the emitted event carries the binding canonical name.
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.
