Option "Whole day" and "Open end" in event contenttype have no meaningful impact

1. go to https://light-theme.kitconcept.io/content-types/event
2. Edit
3. Select either the option "Whole day" or "Open end" in the sidebar
4. Save

-> Both option do not change anything in the view (especially the pre-title metadata shown day/time)
-> As a user I would expect that those options are represented in the view somehow
-> Optional: IMO the option "Whole day" and "Open end" are a bit misleading and quite similar to each other. Also whenever I select "Open end" or "Whole day" it makes the end date/time option redundant. It's a required field in Plone and a conditional rendering of sidebar options is not possible and would also be confusing. But it's still something we should have a look at again.
