- Updated error response codes for various validation errors from 400 to 422 to better reflect the nature of the errors.
- Changed error messages for empty parameters (e.g., userId, menuId, roleId) to use a consistent error code format.
- Improved error handling in the IPerf, Ping, and WS controllers to provide more informative error messages.
