I was just trying to run the server and let it scrape, but it appears to fail after a short while:

Do you know this problem by chance?

The concerned room is 0101.02.133 and the event has the singleEventID 889730446 and starts on 2022-09-28T15:00:00.
It has the status gelöscht, so we might want to skip these kinds of entries anyway

I have fixed this issue.
gelöscht or other unwanted status'es are filtered out in a central place while transitioning from the calendar_scrape to the calendar table, as this seemed cleaner. We can change this design, if you think this would be better ;)

No that's good I think 👍

Thank you for all the effort! I've got only a few comments, else I think it's ready to be merged.
