feat(mesh-phase5): tap the 4 telemetry publish seams into the local hub (DPS intact)

Browse Source 
Each of the four telemetry publish seams now also emits its DPS payload into the
node-local ITelemetryLocalHub (Phase 5), leaving the existing DistributedPubSub
publish untouched:

- driver-health   AkkaDriverHealthPublisher            -> TelemetryItem.Health
- resilience      DriverResilienceStatusPublisherService -> TelemetryItem.Resilience
- alerts          ScriptedAlarmHostActor + DriverHostActor (native) -> TelemetryItem.Alarm
- script-logs     VirtualTagActor + DpsScriptLogPublisher -> TelemetryItem.Script

DI services take the hub as a required ctor param; actors take an optional
nullable hub threaded through their Props and the real spawn sites
(DriverHostActor <- ServiceCollectionExtensions; VirtualTagActor/ScriptedAlarmHostActor
<- DriverHostActor), so existing test Props constructions keep compiling and simply
do not emit. The hub is a no-op until a gRPC client subscribes, so the emit is safe
on every node.
