A second monthly probe exists (restore-drill-media). Its failure was
already covered - BackupJobFailed matches the prefix - but its silence was
not, and silence is the failure this rule set was written against.
RestoreDrillStale now matches the prefix instead of one exact name, and
names the affected probe in the message: with two drills, "the restore
probe has not run" no longer says which. BackupCronJobMissing gains the new
cronjob, because a series that disappears is not an alert in Prometheus,
it is quiet.
