refactor(qr): improve QR code scanning robustness and error handling

Browse Source 
- Enhance JWT extraction with unified path handling and validation
- Add debouncing to prevent duplicate scans
- Improve error handling and logging throughout QR flow
- Add proper TypeScript interfaces for QR scan results
- Implement mobile app lifecycle handlers (pause/resume)
- Enhance logging with structured data and consistent levels
- Clean up scanner resources properly on component destroy
- Split contact handling into separate method for better organization
- Add proper type for UserNameDialog ref

This commit improves the reliability and maintainability of the QR code
scanning functionality while adding better error handling and logging.
