feat(historian): Gateway serves the per-sample aggregates from raw reads with the shared Sql.Common evaluator (#681)

Average, Count, Minimum, Maximum, Range, Start, End, Delta and Minimum/MaximumActualTime are evaluated
on the Gateway backend from forward ReadRaw reads with BucketPlan + AggregateEvaluator, so Gateway
matches SqlServer/QuestDB exactly (values, status bits, interval-start stamps, #677 reverse).

- Window read [start - 1 ms, end] so AVEVA's initial-value row never lands in a bucket; a pre-window
  row proves earlier data only with a non-Bad OPC quality (histsdk puts a value on every NULL row).
- Earlier data otherwise from a 2-row [1970, start) probe; later data from a 2-row [end, now+1d]
  look-ahead; both ignore rows stamped at their query start/end.
- No gateway stream is ever abandoned (a client-side cancel makes the gateway evict its shared
  historian session); past ServerHistorian:MaxTimeWeightedRawRows the bounded stream is drained, then
  BadTooManyOperations. The gateway's max_values-ceiling InvalidArgument maps to the same limit; a
  caller cancellation is not a backend fault.
- TimeAverage/Total stay AVEVA-native (no prior-sample read for exact Part 13 bounds), now stamped with
  the interval start (PENDING the live leg: histsdk's tail+43 start_time field is unverified) and
  carrying the Calculated bits.
- Served set: GatewayHistorianDataSource.ServedAggregates (12). Live AVEVA leg open (VPN).
