The enrich-batch endpoint now accepts a host_ids array alongside ips.
When queue items have no IP address but have a host_id (from ivanti_findings),
the frontend sends host_ids and the backend resolves them via CARD asset-search.
Results include the resolved IP so it populates the IPV4_ADDRESS column.
The LoaderModal now carries _host_id from initialDevices through to the
enrich call.
