[ClassificationStore] Group panel titles are not translated in the object editor

Affected Version

2026.2

Affected capability

Data Objects

Steps to reproduce

1. Open Pimcore Studio.
2. Open (or create) a DataObject class with a ClassificationStore field that has at least one group configured.
3. Add a translation for the group's name key in the studio translation domain for the current admin language (or note the raw group name for comparison).
4. Open a DataObject of that class in the object editor and expand the ClassificationStore field.
5. Observe the group panel's title.

Actual Behavior

The group panel title always shows the raw, untranslated group name, regardless of any translation entry configured for it in the current admin language.

Expected Behavior

The group panel title is passed through the same translation logic as every other panel in the object editor (field collections, object bricks, blocks, regions, etc.) and reflects the translated value for the current admin language when one exists, falling back to the raw name otherwise - consistent with CardView's existing behavior and with the ClassificationStore group name translation available in the legacy ExtJS backend.
