is-Kurt/SPMS-capstone ? reverse-engineered prompt

Build me a simple school portal web app in CodeIgniter 4 for a capstone project.

I want a clean PHP site where an admin can log in, manage students, teachers, classes, and announcements, and see basic dashboard counts. Regular users should be able to sign in, view their profile, and check updates or messages. Make it database driven, with forms for adding, editing, and deleting records, plus simple validation and friendly error messages.

Please keep the design straightforward and responsive, using the default CodeIgniter structure that is already here. Set it up so it works with a MySQL database from a .env file, and include whatever controllers, models, views, and routing are needed to make the main flows work. If you need to check current CodeIgniter docs online, go ahead. Also make sure it runs cleanly without extra setup beyond the usual framework config.
