Status says when the cluster's alerts go nowhere

Setup asks for webhooks, but one left empty was never mentioned again: a
lost node or a judge down was told nobody. With no notify.webhooks in the
cluster's settings, ctl status and the console's Overview say so, and how
to set one. BACKLOG: the judge's refusal after a placement change, tried
again on idle VMs, did not happen; a cold judge's first answer is 2-3x
slower but inside its budget.
