fix(replication): preserve ordered tag deletions

Persist, send and reconcile empty tag states together with their revision
across COPY, PUT and multipart replication. Advance local tag mutations
under the existing locks and preserve current tags during replication ACK.

Cover signed HTTP, persistent single/multiple pool state, KMS, SSE-C key
rotation, ordering, retry and duplicate requests. Record real Opus plan
consensus, implementation review and local verification evidence.
