refactor: replace console.log with logger utility

- Replace all console.log statements with appropriate logger methods in QRScannerDialog.vue
- Replace console.log statements with logger methods in WebDialogQRScanner.ts
- Fix TypeScript type for failsafeTimeout from 'any' to 'unknown'
- Update LogCollector.ts to use 'unknown' type instead of 'any'
- Add eslint-disable comments for console overrides in LogCollector

This change improves logging consistency across the application by using the centralized logger utility, which provides better error handling, log persistence, and environment-aware logging.
