feat: table series avec UUID PK — migration complète backend + frontend

Migration DB (0070 + 0071):
- Backup automatique de book_reading_progress avant migration
- Crée table series (fusion de series_metadata) avec UUID PK
- Ajoute series_id FK à books, external_metadata_links, anilist_series_links,
  available_downloads, download_detection_results
- Supprime les colonnes TEXT legacy et la table series_metadata

Backend API + Indexer:
- Toutes les queries SQL migrées vers series_id FK + JOIN series
- Routes /series/:name → /series/:series_id (UUID)
- Nouvel endpoint GET /series/by-name/:name pour lookup par nom
- match_title_volumes() factorisé entre prowlarr.rs et download_detection.rs
- Fix scheduler.rs: settings → app_settings
- OpenAPI mis à jour avec les nouveaux endpoints

Frontend:
- Routes /libraries/[id]/series/[name] → /series/[seriesId]
- Tous les composants (Edit, Delete, MarkRead, Prowlarr, Metadata,
  ReadingStatus) utilisent seriesId
- compressVolumes() pour afficher T1→3 au lieu de T1 T2 T3
- Titre release en entier (plus de truncate) dans available downloads
