Previously the jq logic checked if *any* review from CTO/QA had
state == APPROVED. This allowed a PR to pass dual-approval even if
the reviewer subsequently requested changes — because the earlier
approval was still in the review history.
Fix: filter reviews by user, take the last one, and check its state.
This ensures a CHANGES_REQUESTED review after an approval correctly
blocks the check.
