### Update CTE Test Cases
- **Added GRPC Latencies Test**: Introduced a new test case for GRPC latencies in `cte.result` and `cte.sql` under `standalone/common/cte`.
- **Removed Redundant Test Files**: Deleted `cte.result` and `cte.sql` under `standalone/common/range` as they were duplicates of the new test case.
