feat(chat): service-level sensitive gating + local sensitive marks

Wires the sensitive-conversation plumbing into ChatService + Settings:
- Settings gains a persisted local sensitive set (isChatSensitive /
  setChatSensitive / sensitiveChatConversations), mirroring the blocked set, for
  INSTANT effect the moment the user marks a conversation (before the on-chain
  signal is harvested back).
- ChatService::isConversationSensitive() OR-combines that local mark with the
  on-chain reduction, and setPersistence() wires it as the DB's per-row key
  selector (sensitive rows -> vault key).
- ingest() withholds a sensitive conversation's messages while the vault key is
  absent (fail-closed: not shown, not persisted); they re-import + persist under
  the vault key once it is unlocked and a scan runs. loadFromDatabase() already
  withholds via the DB's two-key try.
Service-tested end to end against a real ChatDatabase (ingest + reload).

Phase B, step 4 (service gating). App vault lifecycle + UI next.
