recover_interrupted_tasks runs every 5 minutes, finds ImportTask rows
stuck in 'processing' for >30 minutes (well above any legitimate import
duration), and re-queues them. cleanup_old_tasks runs daily and deletes
finished tasks older than 7 days so the task table stays an operational
view rather than an archive.
Both thresholds match ImageRepo's precedent. The 30-min stuck threshold
is documented inline so a future reader can adjust it intentionally
rather than mistaking it for a 'magic number'.

scan_directory walks ImportSettings.import_scan_path, creates an
ImportBatch, enumerates supported files into ImportTasks, and enqueues
import_media_file per task. import_media_file moves the task through
its state machine (pending → queued → processing → complete/skipped/failed),
updates ImportBatch counters atomically (UPDATE ... SET col = col + 1),
enqueues a thumbnail task on success, and marks the batch complete when
the last task drains.
generate_thumbnail runs on its own queue (thumbnail) so big imports
don't starve thumbnail throughput; failure here is logged and does not
fail the import.

Routes are pre-declared for FC-2/FC-3 task modules (import, ml, thumbnail,
download, scan, maintenance). Queue lanes match the ImageRepo pattern where
beat+maintenance run on a separate worker so long imports don't starve
periodic tasks. Smoke ping task confirms the wiring in eager mode for CI.
