Build and store application data

[f1sh1918]

Is your feature request related to a problem? Please describe.
To be able to handle different form formats, we store application data in a json format

Describe the solution you'd like

• bring the application data received from the endpoint in the required json format
• mind that the "name" parameter has to be related to the key in i18n to resolve the correct field label
• fill in some missing static values:
  - cardType ("Blaue Ehrenamtskarte")
  - applicationType ("Verein 360")
  - wantsDigitalCard (true)
  - wantsPhysicalCard (false)
  - category (Sport)
  - hasGivenPermission (true)
  - amountOfWork (5)
  - payment (false)
  - hasAcceptedPrivacyPolicy (true)
  - givenInformationIsCorrectAndComplete (true)
  - hasAcceptedEmailUsage(false)
• add generated accessKey
• add regionId (get by regionIdentifier)
• store application in the database
• store the verification in the database and set the verifiedDate to current timestamp, don't sent email to organization
