Pass query timeout to SessionDataSet when executing query statements instead of reusing connection timeout, preventing large result scans from failing with query-not-found errors.

Description
This PR fixes a timeout propagation issue in the C++ client query path.
Previously, SessionConnection::executeQueryStatement passed connectionTimeoutInMs to SessionDataSet, reusing connection timeout for query result fetching.
For large result scans, this could cause query cleanup during iteration and fail with:
715: Query is not found ...
Fix
Pass timeoutInMs (query timeout) to SessionDataSet instead of connectionTimeoutInMs.
Impact
Prevents Query is not found (715) during long/large query result iteration.
Minimal, single-point change with no API behavior change beyond correct timeout semantics.
