Verify imported Anmeldecodes

[PaulaWi]

As an EAK owner, who received an anmeldecode (QR code), I want to authorize myself in the app to prove my status as EAK owner at accepting businesses.

Acceptance Criteria:

• Generate a OTP from the anmeldecode before persisting it and verify the card.
• Use the query fun verifyCardInProject(project: String, card: CardVerificationModel): Boolean
• Validate that anmeldecode is valid, maybe make a request to the server with a generated hash to check that it actually works
• Owner name, expiry date, random string and otp secret are saved locally in the app

Option to provide recovery information (email address)

@PaulaWi
I would move that to a separate user story. For the beginning it might be a bit too much here.

An additional criteria could be: Tell the user that validation was succesful or that it failed

I think this is quite important. We should warn users if the QR code which was imported is not valid.

This is now high priority because Nuernberg wants to be use the Anmeldecode for verifying that somebody is entitled.

@maxammann Are you still working on this?
I think this would be a good starter task for @f1sh1918 or @sarahsporck

[maxammann]

It would be a shame if I would work on this since 2 months :D

Cool, @f1sh1918 and @sarahsporck : feel free to grab it if you re out of work :P

The issue description is quite old but still largely valid. I think you can ignore the third checkbox, if you don't understand its meaning (I am having a hard time too) :D

[sarahsporck]

Well, then this ticket belongs to me now! :)

We'll most likely get many merge conflicts with #717 . I will help you in fixing them :)
