- GroupRectNode now renders source+target handles on all four sides
(top, right, bottom, left) using IDs zone-{side} / zone-{side}-t
- Handles are hover-only: opacity 0 by default, fade in on mouse enter
- Handle color matches the zone border color (respects custom_colors)
- Zone↔zone and zone↔node connections both allowed; edge type picker
(EdgeModal) opens on connect so user chooses ethernet/wifi/vlan/etc.
- Add GroupRectNode.test.tsx: verifies 8 handles rendered (4 source + 4 target)
- Fix @xyflow/react mocks in LiveView and CanvasContainer tests to include Position
