PR Summary

• Introduction of a New Translation String
  The general.php file located within the en-US language resources, now includes a new translation string referenced as sad_panda. The actual text for this translation reads, 'Sad panda. You are not authorized to do the thing. Maybe <a href=":link">return to the dashboard</a>, or contact your administrator.'.

• Updated Unauthorized Access Message
  In the 403.blade.php error file, the static text message for unauthorized access has been replaced. It now uses the newly introduced sad_panda translation string. This enhancement allows the application to dynamically present the unauthorized access message in different languages.
