User group: permissions grouping (#20584)

* clean up

* localizations

* group user permission by entity type

* adjustments

* fix lint errors

* Support granular permissions without entity type

Updated granular permission handling to allow permissions that are not tied to a specific entity type. Adjusted rendering logic and manifest interface to support undefined or empty forEntityTypes, and added UI for displaying ungrouped granular permissions.

* revert for now
