feat: modale Prowlarr avec bouton remplacer + fix parseur volumes

- Modale Prowlarr (page série) : remplacé le bouton qBittorrent brut
  par QbittorrentDownloadButton avec suivi managé (libraryId,
  seriesName, expectedVolumes) et bouton "télécharger et remplacer".
- Ajout de alwaysShowReplace pour la modale Prowlarr (toujours montrer
  le bouton remplacer) vs la page downloads (seulement si allVolumes >
  expectedVolumes).
- Fix parseur : les tags de version entre crochets [V2], [V3] ne sont
  plus extraits comme volumes (le préfixe "v" est ignoré après "[").
- Progression qBittorrent : utilise directement le champ progress
  (completed et amount_left sont non-fiables sur qBittorrent 4.3.2).
- Référence import : ne plus exclure les volumes attendus de la
  recherche de référence (corrige le mauvais dossier/nommage quand
  tous les volumes sont dans expected_volumes).
- allVolumes ajouté à ProwlarrRelease (backend + frontend).
- flex-wrap sur les pastilles volumes dans la modale Prowlarr.
