Event Self-Check-in and Badge Printout

[mariobehling]

In order to scale up we need an option to provide a self-check-in for attendees and a way to print out badges. Compare here https://youtu.be/-EPC353hLn0

PROCESS
The intended process is as follows:

1. The user has the QR code of their ticket.
2. The QR code gets scanned by a device. The system compares the QR code with the eventyay database.
3. Then on a screen there the user sees a preview of a badge print out that is generated from the data in the system. The user then clicks ok or cancel. In case the user cancels, the user can go back into the system and update details shown on the badge and save them into the system.
4. The badge gets printed out and the user is marked as checked-in.

Please open relevant issues in open event backend as well.

Users who are checked-in should be marked as checked-in on the system as well if the option is not disabled on the event wizard as described here #8683.
