Existing PostAttachments that are actually archives (filed opaquely before the
magic-byte gate) need extracting retroactively. cleanup_service.
reextract_archive_attachments scans PostAttachments, magic-detects the archives,
and for each reconstructs the post's sidecar from the DB + re-runs attach_in_place
in a temp dir — so the members extract and re-link to the SAME post via
find_or_create_post (source_id + external_post_id). Idempotent (members dedupe by
sha256). Enqueues thumbnail+ML for new members.
Wired as a maintenance-queue Celery task (tasks/admin) + POST
/api/admin/maintenance/reextract-archives (202) + a "Re-extract archive
attachments" card in Settings → Maintenance.
Test: a zip stored under a mangled extension-less name extracts + links its
member to the post via ImageProvenance, and a second run is a no-op (idempotent).

- Settings → Maintenance gains a "Database maintenance" card: a "Run VACUUM
ANALYZE now" button (enqueues the maintenance task) plus a per-table bloat
readout (live/dead/dead%/last vacuum) from /api/admin/maintenance/db-stats.
- dbMaintenance store (loadStats / runVacuum) + test.
- Fix ruff I001: combine the two _sync_engine imports onto one line.

Each maintenance button (ML backfill, centroid recompute → ml queue;
thumbnail backfill → thumbnail queue) now shows a status bar with the live
pending count for its Celery queue, so the operator can see work is already
queued/running before re-triggering and piling on. MaintenancePanel polls
/api/system/activity/queues every 4s; QueueStatusBar reads the depth and
turns warning-colored when the queue is busy.

MaintenancePanel hosts: backfill + centroid recompute trigger cards,
the five suggestion-threshold sliders (autosave on slider release),
the allowlist table (inline editable min_confidence, delete), and the
alias table (mapping display, delete). Wired as a third Settings tab,
ML settings loaded lazily when the tab opens.
