feat(runtime): publish DriverHealthChanged via DriverInstanceActor

Browse Source 
- IDriverHealthPublisher in Core.Abstractions + NullDriverHealthPublisher
  no-op for tests/dev-stub paths.
- AkkaDriverHealthPublisher in Runtime forwards to the cluster-wide
  `driver-health` DPS topic.
- DriverInstanceActor instrumented to publish snapshots on every
  observable state change + a periodic 30s heartbeat so the AdminUI
  snapshot store warms up for newly-joined SignalR clients.
- Sliding 5-minute Faulted-count tracked per actor via Queue<DateTime>.
- DriverHostActor.SpawnChild threads clusterId (_localNode.Value) and
  the health publisher down to every DriverInstanceActor child.
- ServiceCollectionExtensions.AddOtOpcUaRuntime registers
  AkkaDriverHealthPublisher as IDriverHealthPublisher singleton.
