fix(historian): #680 lane B — reverse end-of-data Partial (strictly inside), drop dead per-sample Percent cases

Per-sample aggregates (all but Average) now set Partial on a reverse read's interval
that strictly contains the tag's latest sample — the SDK's reverse m_startOfData
(verified vs the SDK harness), matching lane A's time-weighted rule. NeedsDataRange
therefore applies in both directions for every per-sample aggregate but Average.
PercentGood/Bad left the per-sample evaluator (lane A moved them to the time-weighted
family); Evaluate refuses non-per-sample aggregates up front. Comments fixed.
