Major refactor: Replace custom camera implementation with MijickCamera
Added:
- MijickCamera Swift package (v3.0.3)
- MijickTimer dependency (required by MijickCamera)
Changed:
- ContentView now uses MCamera() from MijickCamera
- Ring light wraps around MijickCamera view with padding
- MijickCamera handles all camera logic:
- Permissions
- Capture (photo/video)
- Camera switching
- Orientation/rotation
- Zoom/focus gestures
- Flash
Removed:
- CameraViewModel.swift (replaced by MijickCamera)
- CameraPreview.swift (replaced by MijickCamera)
Kept:
- Ring light background (settings.lightColor)
- Ring size control (settings.ringSize)
- Grid overlay
- Post-capture preview workflow
- Settings view
- Premium features and paywall
- iCloud sync
Benefits:
- Less code to maintain
- Battle-tested camera implementation
- Better rotation handling built-in
- More camera features available (filters, exposure, etc.)
Visual feedback for non-premium users:
- Premium colors show lock overlay with darkened circle
- Crown icon is hollow (outline) when locked, filled when unlocked
- Text is dimmed for locked colors
- Custom color shows rainbow gradient with lock overlay
Interaction behavior:
- Tapping locked premium color opens paywall
- Tapping locked custom color opens paywall
- Non-premium presets (Pure White, Warm Cream) remain fully accessible
- Premium users see unlocked UI with filled crown icons
This helps users:
1. See what premium features are available
2. Easily distinguish free vs premium colors
3. Test both states by toggling ENABLE_DEBUG_PREMIUM env var
