+- `GET /project-devices/projects/:projectId/:projectDeviceId/links`

+- `POST /project-devices/projects/:projectId/:projectDeviceId/synchronize`
+  - applies only explicitly selected fields to explicitly selected linked rows
+- `POST /project-devices/projects/:projectId/:projectDeviceId/disconnect`
+  - disconnects explicitly selected rows without changing their local values

+`displayName` is included in the comparison but is not selected by default in the UI. Updating a
+project device never triggers synchronization implicitly.
