fix(historian): per-sample Average/Min/Max/Range/ActualTime use Good samples only, Part 13 min/max status (#684)
Part 13 defines Average/Minimum/Maximum/Range/*ActualTime over Good raw values (independent of TreatUncertainAsBad) and the SDK's calculators skip Uncertain values under the server's TreatUncertainAsBad=false. SqlServer/QuestDB value columns now use the good flag (g) instead of usable (u); new UncMin/UncMax columns feed the Part 13 Minimum/Maximum/Range status rule (Uncertain on a Bad sample or an Uncertain value beyond the Good extreme -- the SDK applies only the Bad half). An Uncertain-only interval is BadNoData. Uncertain-bearing parity datasets (in-memory + real SQL) match the SDK unmasked; the beyond-extreme divergence is pinned explicitly.
