style(manga-grid): cards sans arrondis, overlay actions au survol, grille plus dense

- Supprime rounded-lg et hover:scale-105 sur MangaCard
- Ajoute overlay gradient + 3 boutons (éditer, sources, rafraîchir) visibles au survol en bas à gauche de la cover
- MangaCard émet les événements edit/sources/refresh vers MangaGrid
- MangaGrid gère les modales et composables (edit, preferredSources, refresh)
- Grille plus dense : cols-3/4/5/7/8 selon breakpoint, gap-2
