feat: add food camera and recognition features
- Implemented FoodCameraScreen for capturing food images with meal type selection. - Created FoodRecognitionScreen for processing and recognizing food images. - Added Redux slice for managing food recognition state and results. - Integrated image upload functionality to cloud storage. - Enhanced UI components for better user experience during food recognition. - Updated FloatingFoodOverlay to navigate to the new camera screen. - Added food recognition service for API interaction. - Improved styling and layout for various components.

- **Navigation**:
|
||||
- File-based routing in `app/` directory with nested layouts
|
||||
- Tab-based navigation with custom styling and haptic feedback
|
||||
- Route constants defined in `constants/Routes.ts`
|
||||
- Route constants defined in `constants/Routes.ts`, every page should use Routes define and jump
|
||||
- **UI System**:
|
||||
- Themed components (`ThemedText`, `ThemedView`) with color scheme support
|
||||
- Custom icon system with `IconSymbol` component for iOS symbols
|
||||
- Reusable UI components in `components/ui/`
|
||||
- UI Colors in `constants/Colors.ts`
|
||||
- **Data Layer**:
|
||||
- API services in `services/` directory with centralized API client
|
||||
- AsyncStorage for local persistence
