- Ajout endpoint manquant /api/notary/document/{id}/status
- Correction erreur BrokenPipeError dans le serveur web
- Création de ressources CSS/JS locales pour éviter les erreurs DNS
- Bootstrap CSS minimal local (bootstrap.min.css)
- Chart.js minimal local (chart.min.js)
- Font Awesome minimal local (fontawesome.min.css)
- Gestion d'erreurs de connexion fermée par le client
- Interface web fonctionnelle sans dépendances externes
- Aperçu PDF avec PDF.js fonctionnel
- Polling de statut des documents opérationnel
