- Cleaned up the scanned result by removing the "lightning:" prefix if present before setting it in the destination field.
- Improved user feedback by ensuring only the cleaned result is processed, enhancing the overall scanning functionality.

These changes enhance the accuracy of QR code scanning results for payment destinations.
