Fixes:
1. Camera preview rounded corners - clipShape now applied before padding
so the preview itself has rounded corners, not the container
2. Debounced slider saves - ringSize and customColor now use debouncing
- Immediate UI update via cached values
- 300ms debounce before cloud save
- Prevents excessive save operations during slider drag
3. Simplified custom color picker to one-step
- ColorPicker styled as a circle button
- Shows current custom color always (no rainbow)
- Tapping opens iOS native color picker directly
- Color applies immediately on selection
- No Apply/Cancel sheet needed
Features:
- Custom color button in Light Color section (rainbow gradient icon)
- Tapping opens color picker sheet with:
- Live color preview
- Native iOS ColorPicker
- Tips for best ring light colors
- Custom color syncs across devices via iCloud
- Premium-gated with crown icon indicator
Storage:
- CustomColorRGB struct for Codable-compatible color storage
- RGB values stored separately in SyncedSettings
- Color converts to/from UIColor for RGB extraction
UI:
- Rainbow gradient when not selected, solid custom color when selected
- Sheet with Apply/Cancel buttons
- Color preview bar at top of picker
Changes:
1. Camera preview now fills available space (not forced square)
- Maintains proper aspect ratio for captured photos
- Controls overlay on top of preview
2. Ring size now limited based on screen dimensions
- Maximum is 1/4 of smaller screen dimension

4. Removed crown icon from main screen
