Joseph Doherty 047988e4c8 feat(siteruntime): Database.CachedWrite emits combined telemetry + S&F audit bridge (#23 M3) ...

Wire the M3 cached-call audit pipeline end-to-end for the database
channel and close the loop between the S&F lifecycle observer and the
site-side dual emitter.

* DatabaseCachedWriteEmissionTests covers Database.CachedWrite (set up
  in Bundle E3): mints a TrackedOperationId, emits one CachedSubmit
  packet on DbOutbound, threads the id into IDatabaseGateway, and is
  best-effort on a thrown forwarder. Mirrors ExternalSystem.CachedCall
  coverage from E3.

* CachedCallLifecycleBridge (new) implements ICachedCallLifecycleObserver
  and lives alongside CachedCallTelemetryForwarder. The bridge ingests
  per-attempt notifications from the S&F retry loop and fans them out
  to the forwarder:
    - TransientFailure -> 1 Attempted row
    - Delivered        -> Attempted + CachedResolve(Delivered)
    - PermanentFailure -> Attempted + CachedResolve(Parked)
    - ParkedMaxRetries -> Attempted + CachedResolve(Parked)
  Channel string -> AuditKind mapping (ApiOutbound->ApiCallCached,
  DbOutbound->DbWriteCached). Best-effort top-level catch swallows any
  unexpected throw so the S&F retry bookkeeping is never disturbed.

* Bridge tests (7) cover all four outcomes, channel mapping, provenance
  propagation, and the no-throw-on-forwarder-failure contract.

Bundle F (Host registration) will instantiate the bridge and inject it
into StoreAndForwardService.cachedCallObserver, closing the wiring path
end-to-end.

Bundle E task E6.
