Subject: [PATCH] Marvis [ FastAPI ] Fix hardcoded CDN URLs in Swagger UI and
 ReDoc HTML generation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pin CDN URLs to specific stable versions instead of major version ranges:
- swagger-ui-dist@5 → swagger-ui-dist@5.20.1
- redoc@2 → redoc@2.7.0

This prevents potential breakage when new major versions introduce
breaking changes to the CDN assets.
