fix(front,db,ci): déploiement web, API même origine, Flutter 3.29, schéma validations

Frontend (prod web):
- Image builder Flutter 3.29.3 (Dockerfile + workflow CI alignés)
- web/index.html: bootstrap Flutter 3.29 (flutter_bootstrap.js), scripts pdf.js conservés
- Dockerfile: rm html avant COPY pour éviter l’index « Welcome to nginx »
- nginx: server_name _ pour Traefik
- env: sur le web, API = Uri.base.origin si pas de API_BASE_URL (évite mixed content http/https)
- auth: message d’erreur réseau avec type/détail si non-Exception
- CGU/PDF: commentaire sans mention Flutter 3.19 obsolète
- pubspec.lock: résolution dépendances Flutter 3.29

Base de données & doc:
- BDD.sql: validations.commentaire, valide_par, FK ON DELETE SET NULL + commentaire
- patch 2026-04-17: valide_par avec ON DELETE SET NULL
- patch 2026-04-18: FK validations en SET NULL sur bases existantes
- seed: statut validation « valide » (enum)
- FK_POLICIES.md: valide_par
- doc workflow: Flutter 3.29.3
