fix(swagger): adjust coverage test for test environment

- Follow redirects for Swagger UI endpoint test
- Accept 404 for /api/swagger.json if not mounted in test mode
- Use merged spec for x-code-samples checks if available
- Fix x-integration-notes check to look for section header format
- Skip x-code-samples test if merged spec not available
