A failed check still calls assessAfterFailure, which now shares one
in-flight assessment between concurrent failures (same cache shape as
ProxyResolver). When egress degrades it upserts a global "egress" job;
DBQueueWorker runs checkRecovery for that type at the configured
interval, and the job deletes its own row once any target answers.
The unref'd timer, startRecoveryPolling, stop and init are gone: a
degraded episode survives a restart through the jobs collection.
deleteByIdAndType accepts a null refId for global rows.
