feat(identity): lazy TMDB lookup and bounded identity pool (DEC-1)

RSS/list releases that match no subscription or local work no longer hit
TMDB or open a pending item; they go to the identity pool as `unmatched`.
TMDB is queried only on a local alias hit, a published new-title rule whose
prefilter passes, manual/Agent retry, search results, or when the new
setting identity.eagerTmdbLookup (default off) is on. Mirrors MoviePilot:
torrents are recognised only when matched to a subscription or searched,
and recognition failures are logged, not alerted.

- Pending items only for related releases (ambiguous after lookup, or
  related to a local work but unresolved); same source + normalized title
  merge into one decision ("来源「X」的 N 条资源待识别"), resolve/dismiss
  applies to the whole group, members detach as they get resolved.
- Pool governance: unmatched reviews capped (daily, 3x), title_alias
  insert trigger wakes similar entries, stale unmatched entries archived
  after identity.poolArchiveDays (30); review idempotency keys include the
  due time.
- Migration 0047_identity_pool: reason/outcome `unmatched`,
  identity_candidate.normalized_title (+trgm index), wake trigger, and
  cleanup of open identity_unresolved items with no related work
  (dismissed, resolution=moved_to_pool).
- Inbox: group by type + work/source with collapse, hide info-only items
  by default (minSeverity=warning), badge counts warning+ only; pool sheet
  gets manual TMDB/local-work assign and dismiss; settings card for the
  new identity settings.
- Runbook docs/runbook/identity.md.

Requires rebuild/restart (migration runs on start).
