feat: initial scaffold — MVP catalogue de données d'API

- Backend NestJS : CRUD api_entries + categories, upload YAML multi-fichiers,
  génération docs AsyncAPI (@asyncapi/cli@6.0.0) et OpenAPI (redocly)
- Fix: route wildcard GET /api/apis/:id/*path pour servir les assets statiques
  (CSS/JS) générés par AsyncAPI HTML template (contournement bug path-to-regexp v8)
- Frontend Angular 19 : pages catalog, browse, api-detail, doc-viewer, upload (DSFR)
- Seeder de données de démo (idempotent)
- Docker Compose dev + Dockerfiles + manifests K8s
- Documentation : README, architecture, référence API REST
