feat: désimport saison/série avec modal, refonte UX épisodes, fix sélection fichier qBit/Transmission

- SerieSeasonCard: remplace le menu burger épisode par corbeille directe, badge Rename cliquable,
  bouton synopsis (ℹ) avec affichage inline, bouton téléchargement masqué si épisode importé
- SerieSeasonCard: modal désimport épisode (avec checkbox suppression fichier) via Teleport
- SerieSeasonCard: bouton corbeille saison + modal désimport saison (avec checkbox suppression fichier)
- SerieView: bouton Désimporter série → modal (remplace dropdown), gère l'emit unimportSeason depuis card
- import.ts: nouvel endpoint DELETE /organized/:serieId/seasons/:seasonId
- qbittorrent: fallback hash pour .torrent sans magnet (snapshot → poll → diff → priorité fichier)
- transmission: fix sélection fichier (trApplyFilePriority async, fileStats→files, files-wanted via torrent-set)
