feat(zigbee): populate IEEE/Vendor/Model/LQI properties on approve and re-import

- Approval (single + bulk) of zigbee pending devices now writes IEEE, Vendor,
  Model, LQI into Node.properties so they show in the right panel.
- Zigbee re-import refreshes properties on existing canvas Nodes and skips
  creating a pending row when the device was already approved — keeps
  approved devices out of pending/hidden modals.
- Coordinator Node also receives the same properties on first creation and
  on re-import.
- Remove the Parent Container selector from the add/edit node modal.
