Renova69/QR_Digital_Menu ? reverse-engineered prompt

Build me a web based QR menu app for restaurants using the stack that is already in this repo. I want two main sides. One is an owner dashboard where a restaurant can sign up, log in, create a restaurant profile, manage tables, build a menu with categories, dishes, prices, images, allergens, and add ons or variations, then generate a QR code for each table. The other side is the customer view, where someone scans the code on their phone, sees the public menu, adds items to a cart, places an order, and can tap a button to call for a waiter.

Please make it responsive for mobile and desktop, with a clean modern UI and a simple flow. Include normal auth, plus Google sign in if it is already supported, order status handling for the restaurant side, and a basic dashboard summary. Wire it up to the Postgres database, expose the API and docs, and make the local dev setup actually run end to end. If anything is unclear, check the repo and current docs online.
