Build me a task management app like Trello where people can sign up, log in, and manage boards with columns for To Do, In Progress, and Done. I want users to create boards, add teammates by email, make cards, edit or delete them, move cards between columns by dragging and dropping, and leave comments on cards. It should also support due dates and labels so the app feels ready for a real team to use.

Use a React frontend and a Node and Express backend with MongoDB for saving data, and make authentication work with JWT and password hashing. I want the app to feel clean and simple, with a smooth dashboard for seeing all boards and opening a board to work on tasks. If you need to check anything, look up the current docs online and build it in a way that is easy to run locally with separate frontend and backend setup.
