fix(historian): record the real status code and typed values; backend-supported kinds gate capture

The recorder now appends the typed HistorianValue and the mux's own StatusCode instead of a
double + hard-coded Good, and drops any kind not in the backend's SupportedKinds (resolved
optionally from IHistorianBackendProvider; absent => {Double, Int64, Boolean}, today's behaviour).
RecorderStatus.DroppedNonNumeric -> DroppedUnsupportedKind; GoodQuality const removed; stale
"mux carries no quality" remarks rewritten (comms-loss node stamps are not historized).
