Adds SiteAlarmStreamEndToEndTests wiring the whole feature pipe with only the
gRPC HTTP/2 transport mocked: real SiteStreamManager.SubscribeSiteAlarms → real
SiteStreamGrpcServer.SubscribeSite → real StreamRelayActor → proto → wire
round-trip (ToByteArray/ParseFrom) → real SiteStreamGrpcClient.ConvertToAlarmEvent
→ real SiteAlarmAggregatorActor cache.
Closes the cross-cutting gap the per-task T1–T6 unit tests leave (each mocks its
neighbour): proves AlarmKey identity (instance, name, sourceRef) + full native
enrichment survive every boundary mapping, attributes and placeholder rows are
dropped end-to-end, the single site-wide stream carries alarms for multiple
instances (no per-instance filter), and a snapshot-seed row and a live delta for
the same native alarm — both mapped through the real pipe — collapse onto one
cache row.
