rdodiya/RestroHub ? reverse-engineered prompt

Build me Restroly, a simple digital menu and restaurant management app for Indian restaurants.

I want a backend and frontend that let a restaurant owner sign in, create and manage menu categories and items, generate a QR menu, and share a public restaurant page that customers can open on their phone. The app should also support UPI payment links and QR codes for common apps like GPay, PhonePe, Paytm, and BHIM. Add an order dashboard so owners can see incoming orders, track them, and view basic analytics like revenue and popular items.

Use a modern React frontend with a clean restaurant style, and a Java backend with PostgreSQL for storing users, menus, and orders. Include secure login, a professional landing page, and a dashboard experience that feels easy for non technical users. If anything is unclear, check the README and look up current docs online if you need to.
