Stef 5b378cad38 Add barcode scanning and meal selection features
Introduces a barcode scanner page using the camera for food item entry, adds routes for selecting meal types and scanning products, and updates the test.html template to allow adding items to specific meals. Also updates branding in base.html, changes the Flask secret key, and enables SSL by default in app.py.
