fix(historian): #680 lane A — time-weighted aggregates follow Part 13

TimeAverage/Total: Uncertain when a Bad value is skipped, an Uncertain value
is used, the value is extrapolated or the interval is not covered; an
interval wholly inside an outage bridges (Uncertain); Total integrates only
the covered part. TimeAverage2/Total2 stop at the end of the data (Partial,
then BadNoData). PercentGood/PercentBad become duration-based and move to
the time-weighted family (now subject to MaxTimeWeightedRawRows). Reverse
reads set Partial on the interval holding the latest sample when nothing
follows (SDK m_startOfData). Parity tests gain end-of-data and outage
datasets; pre-existing #680 masks removed.
