fix(books): tri des séries par volume + suppression de l'ancienne extract_page

- Ajout de `b.volume NULLS LAST` comme première clé de tri dans list_books
  et dans tous les ROW_NUMBER() OVER (...) des CTEs series, pour corriger
  l'ordre des volumes dont les titres varient en format (ex: "Round" vs "R")
- Suppression de l'ancienne extract_page publique et de ses 4 helpers
  (extract_cbz_page_n, extract_cbz_page_n_streaming, extract_cbr_page_n,
  extract_pdf_page_n) remplacés par la nouvelle implémentation avec cache
- Suppression de archive_index_cache dans AppState (remplacé par le cache
  statique CBZ_INDEX_CACHE dans parsers), import StdMutex nettoyé
