PR Summary

• Streamline QR Code Interaction in AssetsController
  The getQrCode method within AssetsController.php was updated. This now incorporates a safety check, meaning it will return false if the QR code type is erroneously set to 'none'. This enhancement makes the system more robust by handling anomalous situations more sophisticatedly.

• Augment UI Feedback with Warning Messages
  The user interface will now exhibit a warning message, decorated in intuitive red color, if QR Codes are active but set to 'none'. This happens in labels.blade.php.

• Optimized QR Code Display Condition
  In the same labels.blade.php file, the logic has been revised to only display the QR code when a valid QR code type is chosen, improving user experience and mitigating potential confusion.

• Introduce new Translatable String for Invalid QR Settings
  A new language string was introduced in general.php that handles situations where the QR code settings might be invalid. This inclusion supports better localization and usability.
