feat: auto-téléchargement par catégorie avec souscription persistante

- Bouton ⬇ sur chaque pill de catégorie pour activer/désactiver l'auto-DL
- Souscriptions sauvegardées en SQLite (table auto_dl_categories)
- Boucle background toutes les AUTO_DL_INTERVAL secondes (défaut 1h)
- Déduplication via already_enqueued() (évite re-queue si déjà queued/done)
- POST /api/auto-dl/check pour déclencher un check immédiat
- GET/POST/DELETE /api/auto-dl/{category} pour gérer les souscriptions
