dnsmasq: ask the resolver a real question, and restart it when it stops answering (hq issue 348)

On 2026-10-09 the control node's dnsmasq stayed active and running, its
journal silent, and refused every question on its private address for
twenty minutes; nothing in the module looked past the unit.

The module is now Go (its TypeScript tools were never served): a root
watch asks the machine's own name on every listen address over UDP and
TCP every 15s, restarts the unit after two failing looks (2 min apart,
3 an hour), and says whether that helped. dnsmasq_health is the watch
process's declared check, so a restart that did not help becomes the
module's unhealthy condition; the service is judged by its unit.
