Replaces separate welcome and server setup screens with a unified 5-page
onboarding carousel that guides users through:
- App introduction and backend requirements
- Notification permission with explanation
- All files access permission with explanation
- Server configuration (address, port, key) with QR scanning
- Completion confirmation
Also adds notification permission checks before uploads to ensure upload
progress notifications can be displayed. Users are prompted for permission
if not already granted, then upload proceeds automatically.

- Create OnboardingScreen.kt with 5-page carousel flow
- Add onboarding completion tracking to PreferencesUtil
- Update navigation to show onboarding on first launch
- Add notification permission checks to upload tabs
- Add roundIcon attribute to manifest for better icon display
- Replace XML layouts with Compose screens for all 5 Activities
- Implement Material 3 theme with Google Blue/Green color scheme matching app icon
- Add device-aware navigation with bottom tabs for Samsung devices
- Remove action bar for modern edge-to-edge UI design
- Update Kotlin to 1.9.22 for Compose Compiler compatibility
- Add Compose dependencies and configure build system
- Implement MainViewModel for upload state management
- Create reusable dialog components for upload parameters and results
- Preserve all existing Java controllers and services (UI-only migration)
Adds QR code scanning functionality to both ServerSetupActivity and
SettingsActivity, allowing users to auto-fill server configuration by
scanning a QR code from the server's admin dashboard.
Changes:
- Add ZXing Android Embedded library (v4.3.0) for QR scanning
- Add CAMERA permission to AndroidManifest
- Create QrServerConfig model to parse and validate QR JSON data
- Create QrScannerUtil for shared scanning functionality
- Extend PermissionUtil with camera permission handling
- Add "Scan QR Code" button to ServerSetupActivity with hint text
- Add "Scan QR Code" button to SettingsActivity
- Add QR scan icon and string resources
- Configure Gradle Java toolchain auto-detection
The QR code contains JSON with server address, port, and client key
which are automatically populated into the input fields when scanned.
