misbahulamin/taskmanagement ? reverse-engineered prompt

Build me a task management web app in .NET 9 using Razor Pages with SQLite, something clean and easy to use for a small team or personal productivity.

I want users to be able to sign up and log in, create tasks, edit them, mark them complete, and keep everything saved in a local SQLite database. Please include a simple dashboard that shows useful stats like total tasks, completed tasks, and what is coming up soon. I also want recurring tasks, so I can set something to repeat daily, weekly, or monthly, and collaborative sharing so one user can share a task with another user.

Make it feel polished and practical, with a straightforward layout, basic validation, and a responsive UI that works well on desktop and mobile. If it helps, look up current docs online for anything needed. Also make sure it is ready to run locally with Docker and easy to deploy later with the database kept persistent.
