- GET /api/auth/me enrichi : avatar, plan actif, subscriptionDate
- GET /api/users/me/profile : profil complet (local UUID, sub, rôles)
- PATCH /api/users/me : update nickname / avatar (validation URL + longueur)
- User entity : champ avatar VARCHAR(500) nullable
- Migration 1742000000000-AddUserAvatar (appliquée VPS)
