Request with set Zone for non 1h tickets

We currently just ignore the zone if it is set in a 24h, 30d or 1y ticket. Other people Interpret it more in the way that the zone is not allowed to be anything but null in those cases. This is why we decided on our aproach but maybe he meant "must not be" insted of "has not to be"?

Task: Clarify what the correct behavior should be. Take appropriate action ☑

Reply: Zone should be empty in both the reuqest and the ticket in the case of a non zone ticket, fixed the openapi definition

Tasks:

• Update to newest newest api
• adjust implementation and tests
