The backend stored the MAC, but the frontend built the approved canvas
node locally with properties=[] (non-zigbee) and no mac field. On save,
canvas/save upserts every node field from the in-memory canvas, so the
empty properties overwrote the DB MAC — the address showed after a
no-save reload but vanished once saved.
Now both approve paths (single + bulk) attach a MAC property row and
the mac field to the node added to the canvas, mirroring the backend
build_mac_property. Hidden by default, toggleable from the right panel.
- new buildMacProperty util + unit tests
- bulk-approve modal test asserts MAC propagation (IP device) and
absence for a zigbee device
