+feat(identity): add an Org Chart tree view to `sys_business_unit`
+
+`sys_business_unit` is already a self-referencing hierarchy
+(`parent_business_unit_id`, ADR-0057 D2) but Setup only exposed flat grids. Adds
+an `org_chart` list view (`type: 'tree'`) that renders the hierarchy as an
+indented, expand/collapse tree-grid, listed first so it's the default tab. No
+schema change — the parent pointer and graph traversal already existed; this only
+surfaces them. The `active` / `inactive` / `by_kind` / `all` grids stay for
+search, filter, and bulk edit.
