Revoke existing cards via HTTP endpoint

[ztefanie]

Is your feature request related to a problem? Please describe.
Adjust the existing HTTP PUT endpoint, so it will revoke existing cards, when the expiration date is set to a date in the past.

Describe the solution you'd like

• Check if a entry in the csv has expiration date in the past
• find the card that is associated with this entry
• revoke the card

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Additional context
For testing:

• Upload a csv with a valid user info
• activate the card in the app
• upload a csv with the same user info, but an expiration date in the past
• open the app: The card should no longer work

@ztefanie i'm not pretty sure if we really need #1419 and #1431 for this.
I think this function will be triggered after each csv import and should just set the card revoked = true . We can just create a proper backend test for testing this.
If the card was activated or not is not important.
In the frontend we already can test the case if a card is revoked that it can't be activated or used. Even we can not test that for koblenz at the moment, i think we can start this task after #1424

@f1sh1918 sure feel free to adjust/edit the text. I like testing issues and everything connected to it, when developing and see no real point of doing this before the other tickets, but feel free to do so, if you have a strong opinion on this.
