fix: placement boutons Tarot/Actions/Épreuve dans le chat FVTT v14

- insertion en haut de #chat (avant sidebar-tab-core) au lieu
  d'insérer avant #chat-controls (caché par le scroll en v14)
- remplacement inline styles → classes CSS .hamalron-chat-tools/.hamalron-chat-btn
- CSS externalisé dans chat.less
