Build me a simple Faiba Mobile app with a matching backend so a user can open it, sign in, and manage their mobile account in one place.

I want it to feel clean and easy to use, with a home screen that shows the main account details, basic plan or usage info, and a few common actions like checking status, viewing messages or notifications, and updating account settings. Make the backend handle the user data and app requests in a straightforward way, and set things up so the frontend and backend work together smoothly.

Keep the design modern but simple, something that would work well on a phone. If you need to look up current docs online for anything, do that. Please build the full thing so it runs end to end and is easy to test locally.
