Add comprehensive API documentation for ThrillWiki integration and features

- Introduced Next.js integration guide for ThrillWiki API, detailing authentication, core domain APIs, data structures, and implementation patterns.
- Documented the migration to Rich Choice Objects, highlighting changes for frontend developers and enhanced metadata availability.
- Fixed the missing `get_by_slug` method in the Ride model, ensuring proper functionality of ride detail endpoints.
- Created a test script to verify manufacturer syncing with ride models, ensuring data integrity across related models.
