Build me a polished task management web app called TaskFlow.

I want users to be able to register, log in, and then land on the right dashboard depending on whether they are a normal user or an admin. Regular users should be able to create tasks, edit and delete only their own tasks, mark task status, search and filter tasks, and see a dashboard with simple charts and stats like todo, in progress, completed, overdue, and high priority. Admins should be able to see all users and all tasks, assign tasks to any user, change roles, update or delete users, and manage every task.

Please make it look modern and clean, responsive on desktop and mobile, and include dark mode. I also want profile editing with name and avatar URL, good loading and error states, and clear confirmations for destructive actions. If you need to look up current best practices or docs while building it, go ahead.
