De-coupled web and mobile QR scanner views

- Separate scanner views for web and mobile platforms: different libraries, similar layouts
- Mobile: QR code overlaid on top of full-screen camera view
- Mobile: added framing box + instruction text
- Mobile: increased debounce time to compensate for behavior of MLkit scanner
- Web: removed Capacitor-related code and platform-specific conditions
- Web: adjusted max-size of QR code and camera view to better fit newer iOS device screens
- Web + mobile: camera view remains active when a QR scan is triggered
