Application complète SLUC Business Club (React + Express + PostgreSQL, Docker)

Implémente l'intégralité de la maquette « SLUC Business Club.dc.html » :
- Site public : accueil (héro administrable, carrousel membres, agenda avec
  inscription en ligne, rencontres passées, demande d'adhésion), annuaire
  avec recherche/filtres/fiche détaillée, page association
- Espace membre : connexion, édition de fiche avec aperçu direct, upload
  logo/photo, statut d'adhésion par saison, changement de mot de passe
- Espace admin : tableau de bord, membres (validation par saison),
  rencontres (CRUD + inscrits + impression + export Excel), inscriptions,
  catégories, contenu du site

Architecture : 3 conteneurs Docker Compose — PostgreSQL 16 (réseau interne,
rôle applicatif restreint), API Express (non-root, read-only fs), nginx
non privilégié (frontend React + reverse-proxy + CSP stricte).

Sécurité : requêtes 100 % paramétrées, bcrypt + JWT httpOnly SameSite=Strict,
vérification d'Origin (CSRF), validation zod, rate limiting, uploads vérifiés
par octets magiques avec noms aléatoires, aucun secret committé.
