GrapickArsip/absensi-sekolah-qr-code ? reverse-engineered prompt

Build me a school attendance web app that lets students and teachers check in with a QR code, and also supports RFID cards as an alternative.

I want an admin login, a dashboard to see attendance in real time, and pages to manage students, teachers, classes, and staff. Please include the ability to generate and print unique QR codes for each person, export attendance reports to PDF, import data from CSV, and edit attendance records when needed.

It should also handle leave and sick requests from a public page, let people check their own attendance history without logging in, send WhatsApp notifications after a successful check in, and track late arrivals with a simple points system. Add holiday settings, workday settings, backup and restore, and an audit log for changes. Use the current docs online if you need to confirm anything.
