refactor: Remove unused JWT validation and extraction functions

- Removed unused functions for JWT token validation and extraction
  from the `AuthController`.  This simplifies the codebase and
  removes unnecessary dependencies.
- Improved error handling during user JSON parsing in login and
  registration controllers, adding more informative log messages.
- Updated user model to remove unnecessary password fields.  This
  reduces data storage and improves security by not storing
  sensitive information unnecessarily.
- Added more robust error handling and logging for JSON parsing in
  the home and auth controllers.  This helps in debugging and
  monitoring potential issues during runtime.
