feat(service): P5.3 inbound adapter pipeline (ACK-fast webhook + RawEventProjector) + traceId

POST /v1/adapters/:type/webhook verifies HMAC (fail-closed) -> stores raw ->
emits raw.received -> 202. RawEventProjector consumes it off the relay, normalizes
via the adapter, reuses IngestService (traceId threaded raw->interaction).
Deduped on (channelType, externalEventId). rawBody enabled. 48 tests.
