Build me a simple task management app where people can sign up, log in, and keep track of their tasks in one place.

I want a clean dashboard where users can add, edit, delete, and mark tasks as done, and only see their own data after signing in. If it makes sense, include a small weather panel on the dashboard and basic email notifications for task related reminders or updates. Make the app feel polished and easy to use on desktop and mobile.

Please wire up the backend, database models, auth, and the main dashboard screen so it all works together. If you need to check current docs or best practices for anything, go ahead and look them up online.
