feat: enhance API route naming conventions and structure

- Added comprehensive guidelines for API route naming and structure in `ROUTE_NAMING_BEST_PRACTICES.md`.
- Updated `ARCHITECHTURE.md` to reference the new best practices document.
- Refactored course-related routes to follow new naming conventions, including changes to endpoint paths and validation schemas.
- Removed the deprecated course clone route and integrated cloning functionality directly into the course routes.
- Adjusted various API methods to ensure consistent usage of HTTP methods and parameter structures across the application.
