* feat(#350): pairing login flow with QR scan + manual entry
Adds PairingCodeEntryScreen with CameraX + ML Kit QR scanning
and manual code entry. The screen parses hermes://connect URIs,
Base64-encoded JSON, and raw token formats, validates via
/api/status, and saves credentials on success.
- New PairingCodeEntryScreen + PairingCodeEntryViewModel
- CameraX 1.4.1 + ML Kit barcode-scanning 17.3.0
- CAMERA permission + proguard rules
- Landing screen Pairing Login button wired correctly
* fix(#350): resolve smart-cast on delegated property for errorMessage

* refactor(#421): remove QR scanner from pairing login
- Remove CameraX + ML Kit barcode dependencies
- Drop CAMERA permission and camera feature from manifest
- Strip QrScannerTab, QrCodeScannerView, processFrame composables
- Remove camera permission state/methods from ViewModel
- Purge all QR/camera strings from strings.xml
- Delete ML Kit proguard rules
The pairing login now shows only the manual code entry UI.
