Display of metadata

Within this user story, we want to define how the metadata of model runs and users/groups is displayed in the model data explorer. We want to define:

1. How the metadata fields from #18 are displayed
2. How relations are displayed (see #17)

We will have two meetings. One, where the developers show their approach in the Figma prototype and discuss it with the scientists. The developer team will then revise the prototype and show another version to the scientists in a second meeting.
