feat: nommage UNFR -ReMoRa automatique après téléchargement

Format : Title.Event.Year.FRENCH.Resolution.WEBRip.x264|HEVC.AAC-ReMoRa.mp4

- build_release_name() : slugify avec strip accents, apostrophe→point,
  déduplique l'année si présente dans le titre ET passée séparément,
  détecte la résolution et le codec depuis les infos yt-dlp
- enqueue() : reçoit subtitle + year depuis l'API
- _run() : renomme le fichier après download, met à jour le filename en DB
- DownloadRequest : subtitle + year ajoutés
- app.js : extrait l'année du subtitle via regex avant d'envoyer la requête
