Task 10: Device filter now combines games with platform support entries
AND games with performance entries for the selected hardware, instead of
only checking gamePlatformSupport. This ensures games that have benchmarks
but no explicit platform support entry still appear in filtered results.
Task 11: The benchmark count query (bCounts) in unified search now filters
out soft-deleted performance entries using isRemoved = false. The pCounts
and perfStats queries already had this filter; only bCounts was missing it.
