Marvis [ FastAPI ] Fix hardcoded CDN URLs in Swagger UI and ReDoc HTML generation

Pin CDN URLs to specific stable versions instead of major version ranges:
- swagger-ui-dist@5 → [email protected]
- redoc@2 → [email protected]

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