Build me a full stack student productivity app called STUDENT FLOW where students can sign up, log in, and keep track of assignments, daily tasks, study sessions, and academic calendar events all in one place.

I want two roles, student and admin. Students should only see and manage their own data, while admins can view all students, search and filter them, see basic activity stats, and activate or deactivate accounts. Students should be able to add, edit, delete, and mark tasks complete, manage assignments with deadlines and priority, record study time with a simple focus timer or manual session log, and view a dashboard that shows upcoming deadlines, pending work, and productivity stats.

Make it feel clean and modern, with a landing page, login, signup, student dashboard, admin dashboard, profile page, assignments, tasks, calendar, and productivity pages. Use secure token based login and protected routes. If you need to check any current docs while building it, go ahead and look them up online.
