Chaîne de résolution metadata (local, Open Library, Google Books, BNF) avec activation/priorité/clé API par provider, colonnes isbn13 et identifiers sur les livres, et intégration au scanner pour compléter métadonnées et jaquettes manquantes. Module automation: réglages persistés, planifications scan/enrichissement et déclenchement manuel, exposés via des endpoints admin. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
