fix(swagger): use merged spec for integration-notes check

- Skip x-integration-notes test if merged spec not available
- The YAML file only has path placeholders without detailed descriptions
- JSDoc comments with x-integration-notes are merged at runtime
- Test will skip gracefully when /api/swagger.json returns 404
