- MailInternalDto accepts attachments[]; deposit() stores each as a media
part (image/video→MEDIA_REF, audio→VOICE_REF, else FILE_REF)
- ingest now persists part sizeBytes; contract + DTO carry it
- threads.getMessages returns mimeType + sizeBytes so mail readers can
render inline images / file chips
- test: internal mail stores an image attachment as a MEDIA_REF part

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.
