Build me a full stack student management app where users can sign up, log in, and stay signed in with secure token based auth. After logging in, they should see a protected dashboard where they can add students with name, email, age, and course, then view, edit, and delete those records from a live list.

I want the student list to update right away and include a search box so I can filter by name or course as I type. Please include clear loading states, error messages, and form validation so the app feels polished and easy to use. Use a MongoDB backed API with a React frontend, and make sure the app is split into a backend and frontend the normal way. If you need to check current best practices for setup or auth handling, look them up online as you build it.
