Option to limit scrolling the weekview when Untis data allowed to seen is limited

[MatsG23]

Problem Statement

Many schools limit the visibility of the Untis timetable data to, like a time frame of a week (ahead and backwards), for standard users. This is because the future plan would sometimes be full of gaps yet (if teachers are missing) and things are non-final yet.

Solution Ideas

The app could limit the viewable time frame in the week view to e.g. one week backwards and ahead that is inaccessible (empty).
