`General`: Web version for attendance check

[az108]

Is your feature request related to a problem?

Currently, attendance can only be checked using the ArtemisChecker app, which has some drawbacks. For example, each chair must provide a sufficient number of iPads and is required to conduct attendance checks exclusively through the app, which can be challenging for large courses.

Describe the solution you'd like:

A simplified attendance check mode that can be used on a smartphone. This mode would retain the existing functionality to check all students and trigger a pop-up on their screens during the exam via an attendance check button. Other functionalities, such as signing and ID verification, would be optional. With fewer data points displayed (only an attendance button for each student), the interface should also fit well on a smartphone screen.

This solution would benefit chairs who cannot afford multiple iPads, allowing them to conduct attendance checks on paper while still ensuring students confirm their presence digitally, helping prevent cheating.
