feat(studio/robot-authors): category filter + display_name & category columns

- searchable CategoryPicker (Popover+Command) reusable across studio pages,
  plus useCategoryOptions hook (shared tree query + id→name resolver)
- filter bar with category + status filters and a reset action
- new columns: account (avatar + display_name + uid), category name; persona
  demoted to a secondary column; display_name/category surfaced in detail sheet
