Build me a full stack task manager web app where I can add tasks, edit the title inline, delete them, and mark them as complete or move them back to active. I want it to save everything in MongoDB, including when each task was created and completed, and show simple stats for active and completed tasks.

Please make the task list easy to filter by status and by time range like today, this week, this month, or all tasks. Add client side pagination so long lists are still easy to use. I also want clear success and error messages when I do something.

Use a clean responsive interface that looks good on desktop and mobile, and make sure the frontend talks to a backend API properly. If needed, look up current docs online for anything you need, and set it up so the React app can be served through Express in production too.
