Improve Collection creator UI

[JJ-Author]

• [x] include the new search type filter component from #110 when adding a new item

collection group facet configuration:

• [x] show name of the group which is configured
• [x] render the list of artifacts which are selected for the group being edited
• [ ] show the number of files per artifact which are returned based on group facet selection vs overwritten facet selection (if any)?? (should be fetched async in order to not slow down UI experience)

collection artifact facet configuration:

• [x] show name of the artifact which is configured
• [x] Select latest version as default

I am not sure about the remaining suggestions, this would do a LOT of querying in the background. The 'show numbers' thing at least.

yeah I agree. The new experience is great. But when you click on a group in the collection you get this list with artifacts and the group filter selection. I think at this place it could make sense to give this information, how many files are selected by group and how many are returned by artifact based on overriden selection? but potentially you are right an this will trigger a lot of queries. maybe sth for backlog?
