fix(historian): #684 review — Uncertain non-numeric samples do not refuse the Good-value aggregates; real-SQL Uncertain-above-max test

- Average/Minimum/Maximum/Range/*ActualTime refuse (BadAggregateInvalidInputs) only a GOOD
  String/DateTime sample (new GoodNonNumericCount / good_non_numeric_count column); an Uncertain
  one is skipped and makes the min/max family Uncertain, matching the SDK (Average skips it,
  ComputeMinMax flags the uncastable value). Delta keeps its usable-sample refusal.
- ProcessedConformance: an Uncertain value above the Good maximum (pins UncMax/unc_max through
  the real SQL) and an Uncertain String through the real SQL.
- The_uncertain_dataset_is_not_vacuous also proves the min/max STATUS discrimination.
