tasks app

[pervezfunctor]

We need to implement a minimal full stack application with authentication using all libraries in devfractal.

Use drizzle-orm to implement the following tables and relationships.

1. Student can be part of many Courses.
2. Teacher can teach many Courses.
3. Each Course has many Tasks.
4. Users can be Student, Teacher or Admin.

Business Rules

1. Only admins can create courses, teachers and students.
2. Only admins can assign students and teachers to courses.
3. Teachers can create tasks for their courses.
4. Students can only read tasks from their courses.
