cellxgene_census.open_soma() was never closed in extract_czi_markers, leaking the SOMA connection. Wrap the census usage in try/finally to ensure census.close() is always called, matching the pattern already used in download_czi_reference.

LGTM — fixes SOMA connection leak. try/finally is correct; could use a context manager in a future cleanup but not blocking.
