sandbox-proj/technical-assessment ? reverse-engineered prompt

Build me a full student management web app for a school, with a clean admin dashboard, login, student management, staff management, classes, notices, and leave requests.

I want the frontend to feel polished and easy to use, with forms, tables, and validation, and the backend to handle the full CRUD flows and talk to a PostgreSQL database. Please make sure the student records can be created, viewed, edited, and deleted properly, and that notice creation works correctly, including saving the description field.

Use the existing project structure if it helps, and wire everything so I can run the app locally with the database seeded from the provided SQL files. If you need to check current docs for anything, feel free to look them up online.
