feat(manga): implémenter la page Découvrir avec recommandations MangaDex

- Endpoint GET /api/manga-discover via DiscoverMangaStateProvider + DiscoverMangaHandler - Algorithme : top 5 manga de la collection → appel /manga/{id}/recommendation par source → agrégation avec système de votes (multi-sources = plus pertinent) - Filtrage : tags exclus (Oneshot, Doujinshi, Self-Published), contentRating, et suppression des manga déjà en bibliothèque - Page Vue DiscoverPage.vue : chargement auto au montage, bouton Actualiser, modal détail, ajout à la bibliothèque - Adapteurs InMemory de test mis à jour (discover + getMangaRecommendations)
