done column: 'verify N' header button to backfill ✓ → ✓✓

new POST /api/execute/verify-unverified that picks every plan with
status=done + verified=0 and runs handOffToJellyfin sequentially in
the background. each handoff fires the existing plan_update sse so
the done column promotes cards as jellyfin's verdict lands. exported
handOffToJellyfin so the route can reuse the same flow as a fresh job.

done column header shows a 'Verify N' action whenever there are
unverified done plans, alongside the existing 'Clear'. one click and
the user can backfill ✓✓ across every legacy done item without
re-transcoding.
