fix: toolbar carnet redesign — propre et cohérent

- Layout mode (Grid/List/Table/Kanban) déplacé à droite
- Sort à droite avec icône compacte
- Toutes les actions IA (Résumé, Planning, Organiser) + CSV dans un menu ⋯
- Plus de boutons éparpillés — tout est dans un seul dropdown
- Layout respecte le design system existant
