Refactor tests: update input path resolution, optimize imports, and enhance load_ifc_occ_shape.

Simplify path definitions in `test_write.py` and `test_open.py`. Replace `typing` with `collections.abc` for `Sequence` usage in `test_sweeps.py` and adjust type hints to use Python's generic collections. Add optional verbosity to `load_ifc_occ_shape` and refine geometry test assertions. Update `simple_sweep_2.ifc` fixtures for consistency with test expectations.
