Add Captcha handlers to OpenAPI routing

- Integrated Captcha functionality by adding a new route for captcha handlers within the OpenAPI structure.
- Updated the Attach method to include the Captcha endpoint, ensuring OAuth protection for the new route.
- Enhanced overall routing organization by grouping captcha-related handlers under a dedicated path.
