feat(downloads): Unverified review filter + visible retry progress

- '⚠ Unverified' filter pill on the Downloads page lists completed downloads
  whose verification status is unverified/force_imported (review queue)
- the quarantine-retry engine's attempt counter (already tracked internally)
  is now surfaced: task.retry_info ('2/5') shows next to Searching/Downloading
  in the modal and as 🔁 on the Downloads page rows, with the trigger in the
  tooltip
