fix: motivation dossier famille à l’inscription + servir /uploads + Traefik

- Inscription parent: créer dossier_famille + dossier_famille_enfants (presentation_dossier)
- Nest: useStaticAssets sur le volume uploads (chemins /uploads/photos/…)
- docker-compose: route Traefik PathPrefix /uploads → API (priorité 18)
- Front: ParentDossier.id depuis user_id (aligné API)
