feat(browse): gestion CRUD des dossiers depuis la page Browse

- Ajout boutons Modifier/Supprimer sur chaque tuile de dossier
- Supprimer visible uniquement si dossier vide (0 APIs, 0 sous-dossiers)
- Modale Angular (sans fr-modal DSFR) pour créer/éditer un dossier
- Backend: remove() lève BadRequestException si dossier non vide
- Ajout fichiers YAML de démo (OpenAPI Petstore, AsyncAPI User Events)
