feat: UI de configuration des colonnes et mappings label→colonne

- Bouton ⚙ sur chaque colonne pour configurer le mapping label Gitea
- Modal ⚙ Colonnes pour ajouter/renommer/supprimer des colonnes
- API DELETE /api/col-mapping pour supprimer un mapping
- Rafraîchit le board après chaque modification de colonne/mapping
- CSS pour les nouveaux éléments (config panel, column list)
