linuxmuster/linuxmuster-webui7 ? reverse-engineered prompt

Build me a web interface for linuxmuster.net v7 that school admins and teachers can use to manage everything in one place.

It should have a clean login screen, then pages for user management, device management, class and project management for teachers, school quota and settings, and Linbo management. I want it to feel like an admin dashboard that makes common school IT tasks easy to browse, edit, and save without needing to use the command line.

Please make it look polished and practical, with a simple navigation layout and clear forms, tables, and status views for the main areas. If you need to check the latest docs or best practices for linuxmuster.net, look them up online first. Also include a few realistic screens or sample data so the interface feels complete and usable right away.
