Build me a simple shop management app for Kedai Mas Amba with a backend and a Flutter app.

I want users to be able to register and log in, then see different access based on role, like admin and regular user. The app should let me manage categories, products, and transactions from the mobile app, with data coming from an API. Products should support adding a photo, and I want the images to show up properly after upload.

Please also include a way to save the login token so users stay signed in, and make the app connect to the local backend easily. For the backend, set up the basic API routes for authentication, categories, products, and transactions, and make sure protected pages only work when the user is logged in.

If you can, add export to Excel for products and categories too. Keep the UI simple and usable, and if you need current docs for Flutter or Express, look them up online.
