Introduces a new /scan route and template for barcode scanning using ZXing in the browser. Adds a /nutri/<barcode> API endpoint to fetch food item nutrition data by barcode. Updates the FoodItem model to include a barcode field and a to_dict method for JSON serialization. Also updates seed data to include a barcode.
