DriverStatusPanel (the /hosts Controls dialog) showed one snapshot per driver - the most
recently published across both nodes of the redundant pair - so a driver Faulted on one node
and Healthy on its peer flipped on every publish. It now primes from the store's GetAll() and
keeps one entry per ReportingNodeId (DriverStatusByNode): per-node state chip in the header,
per-node last-success / 5-min errors / last error, per-node stale dimming. A snapshot with no
node id (pre-#847 publisher) renders unlabelled, sorted last. A primed copy older than a racing
live publish for the same node is dropped.
