not possible to delete expiration for api keys anymore over UI
Previously I was able to delete the expiration date when creating API key. This seems to not work anymore in both Firefox and Chromium but it was never obvious that it is possible.
- AC1: It is possible to create API keys without expiration over the UI
- AC2: It is obvious to the user that no expiration is a possibility
- Add a test for this
- Allow to set no expiration, e.g. by allowing to delete the date from the entry field or even make that more explicit
- Test manually with usual browsers
