BasketScreen class
Screen displaying the user's current shopping basket with item management.
Shows all products added via ScanScreen with their quantities and provides controls to:
- Increment quantity (AppState.incrementItem)
- Decrement quantity (AppState.decrementItem)
- View total item count
Items are grouped by product (UPC) with quantity controls. When quantity reaches zero, the item is automatically removed from AppState.basket.
This screen watches AppState for real-time updates when items are modified from other screens or when barcode scanning adds new products.
Usage: Navigated to via /basket route or the basket summary card
in ScanScreen.
