fix: broken import in test_kis_data_collection_v1.py (same root cause as F8)

Same class of bug as the earlier tools/run_kis_data_collection_v1.py
fix this session: the module moved to src/quant_engine/deprecated/
but this test still imported the old path. Found by actually running
pytest --collect-only on tests/unit/ (110 tests collect cleanly now,
was failing at 1 error before).
