feat: show core relations in infobox

To reduce clutter in show and list views, display of core relations has been adjusted.

Show mode:

Core relations such as eid, creation and modification date are shown in an information box. There is a new configuration option to allow disabling it or overriding it with a custom React component. Core relations can still be shown in the main view using configuration.

The owned_by relation has a cardinality of ** so the component is a list. To prevent the large list from showing in the small info box, a button is displayed instead which brings the full list in a dialog when clicked.

List mode:

Only the eid, creation and modification date core relations are shown. Unless configured otherwise, the eid relation is shown in first (from the left), and the dates last.
