Part of #15's fourth piece: on-demand active investigation of a
single unknown device, admin-triggered from the dashboard. mDNS
resolve, targeted SSDP/UPnP query (many smart-home devices announce a
friendlyName/manufacturer this way), curated port scan, HTTP
title/server grab on anything open. Runs on the CT122 host for the
same multicast-needs-real-network-access reason discover-devices.sh
does. Not wired into the API yet -- that's next.
