Pattern #4 DANVA: fix ruff format on _calibration.py

Same root cause as Pattern #2 fix: format pass missed a file edited
after the previous format. CI lint rejected the unformatted file.

I need to start adding a pre-commit hook locally so this stops happening.

No semantic changes -- pure whitespace.
