[Add] When I add a value with unit it should not be possible to enter a URI via the UI. It is only possible to select an Item that represents the unit.
[Edit] When I edit a value with a unit:
- **Wikidata concept URIs :** it should never show the URI instead the label always is shown.
- **Some URI:** it should show the URI and it should allow me to edit the value, but it is only possible to change the URI by selecting an item. (old Data/imports/errors)
In essence this means it is only possible to enter non vocabulary repo concept URIs via the API, but there must be a configuration that allows to reject non concept URIs of the vocabulary lookup repository.
Keep in mind:
In the future it should be possible to configure a remote vocabulary lookup repository that has the same behavior as on Wikidata (selecting, label resolving)
