test(gfql): probe to_dicts before to_dict(orient=) for engine-agnostic records

The dual-path guards checked hasattr(out, 'to_dict') first, but polars
DataFrame HAS to_dict (without orient) — so the polars branch was
unreachable and these tests only ever ran because auto silently returned
pandas. With auto routing polars-frame graphs natively they now receive
polars frames; probe to_dicts first. Assertions (record values) unchanged
and still pass on both engines.
