mzb000/task-management-system — reverse-engineered prompt

Build me a polished task management web app called TaskFlow that feels production ready. I want a React frontend, a FastAPI backend, and a PostgreSQL database, and it should be easy to run with Docker. Users should be able to sign up, log in, log out, reset their password by email in dev mode, and have either admin or regular user access.

The main app should let people create, edit, delete, search, filter, sort, and mark tasks complete, with fields like title, description, due date, priority, status, tags, attachments, and comments with username mentions. Please include a dashboard with totals, overdue and completion stats, charts, and a recent activity feed.

I also want profile editing with bio, avatar upload, password change, workspaces with member invites, in app notifications with unread counts, and activity logs. Make the UI feel smooth and modern with nice animations, protected pages, and working API docs. Use sensible defaults, and look up current docs online if you need to.
