feat: atomic social local writes, remote review enrichment

SocialCommand methods take events. Local follow ops = one FollowCommand::apply
tx (rows + events). k_ap path (remote, block/unblock): best-effort publish in
CompositeSocialAdapter after k_ap write; not atomic, k_ap owns tx.
save_remote_review takes events, enqueued in same tx via
sqlite::persistence::enqueue_events. Deps drop event_publisher: social
command, ReviewObjectHandler.

Remaining .publish( sites:
announce-only: users/delete_account UserDeleted, person/get + get_credits
PersonEnrichmentRequested, jobs/enrichment_staleness, http-axum search,
ImageStored (sync_poster, poster_sync_handler, image-converter backfill,
update_profile; object storage), federation_event_bridge (handler reaction),
nats relay (transport).
non-atomic by necessity: CompositeSocialAdapter::announce (k_ap-owned write).
Everything else rides its write.
