Change le mapping des ports hôte vers des ports peu courants

- App : 8413 (hôte) → 3000 (conteneur)
- Postgres : 54329 (hôte) → 5432 (conteneur)
AUTH_URL, .env.example et README mis à jour en conséquence. Les ports internes
des conteneurs (3000, 5432) et DATABASE_URL (réseau interne) restent inchangés.
