style(test_suod): strip CRLF from TestSUODOptionalImport block

Cleanup follow-up to #676. The new test block landed with CRLF line
endings (likely a contributor-side editor / git config artifact) and
was the only section flagged by `git diff --cached --check` as
trailing whitespace. Normalizes only the new block to LF; the rest of
the file keeps its existing CRLF until a broader normalization pass.
No behavior change.
