nudgeValues filled {service} from State.Fact("service_down"), an exact key
mavpoll stopped writing when per-monitor facts landed. The lookup could never
hit, so every variant carrying {service} was rejected as unfillable and the one
nameless variant was the only usable template, every time. A sev4 reaching him
on telegram said only that a service was down.
It now reads loop.DownServices, the same helper the rule fires on, so the
message cannot name a service that is up. Dropped the nameless variant and the
{since} one: service_down facts are keyed by monitor and the rule is
edge-triggered, so neither can fill. service_down joins routine and morning as
a family that always carries a name.
The tests passed through all of this because cand() built the pre-per-monitor
aggregate shape. downCand() builds what a tick actually produces.
