fix: images, couverture, slash, agents, wizard, Stripe et admin

- Collage/accès images: ownership path userId + meta legacy, 403 non caché
- Couverture note: explicite (choix/aucune), plus d’auto depuis le corps
- Éditeur: suppression image TipTap, sync immédiate, toolbar réordonnée
- Slash: listes par titre (plus d’index), keywords nettoyés
- Agents: nextRun à la réactivation, cron sans stampede null
- Wizard: titres courts + mode Expert plus robuste
- Stripe checkout hosted fiable; admin métriques live; dark mode IA/settings
- Indexation notes courtes + test unit aligné
