- Updated API routes to use a unified versioning scheme under `/api/v1/auth`.
- Implemented new authentication controller for login, registration, and token management.
- Removed legacy user and index controllers, along with associated models and validation files.
- Updated documentation to reflect new API endpoints and usage.
- Cleaned up unused service and middleware files to streamline the application structure.
