refactor: enhance OpenAPI integration and security handling

- Updated GetOpenAPI function to improve clarity by storing the Fizz instance in a variable.
- Added security middleware to FizzWrapper for API token authentication, enhancing security measures.
- Configured sorting of tags in the OpenAPI generator to maintain consistency in API documentation.
- Improved comments for better understanding of the changes made in the OpenAPI wrapper.
