style(sidebar): supprimer Calendrier, corriger isActive, séparer toggle/nav, harmoniser hover

- Retrait de l'entrée "Calendrier" du menu et de sa route Vue Router
- isActive inclut désormais les sous-items (fix: groupe Mangas actif sur /import)
- Chevron déplacé dans un <button> séparé du RouterLink (plus de double toggle/nav)
- Hover harmonisé : hover:bg-gray-700 + hover:text-white sur parent et sous-items
