- Tree structure: clients rendered as indented tree with visual connectors
- Expand/collapse: chevron toggle, children count badge, expand/collapse all
- Parent selector: dropdown on add + "Move..." inline picker on each client
(excludes self and descendants to prevent circular refs)
- Search: shows matching clients AND their ancestors for context
- Depth visualization: alternating backgrounds, border-l connectors
- Drag-and-drop: preserved, reorders among siblings only
No API changes needed — router already supported parentId in CRUD.
