### What problem does this PR solve? Problem Summary: `external_table_p0/hive/test_hive_compress_type.groovy` had a fixed split assertion (`28`) for multi-BE, which is not stable across environments. The split behavior for COUNT pushdown depends on both `backendNum` and `parallel_fragment_exec_instance_num`, so internal 3BE pipeline could still produce `16` and fail. This PR makes the assertion BE-aware and deterministic: - read `backendNum` via `show backends` - read `parallel_fragment_exec_instance_num` via `show variables` - compute expected split count with the same condition as FE logic - add comments to explain why this check differs between environments
