fix: lint the artifact scorer — import order and line length

The artifact-level scoring tool landed with an unsorted import block
(I001) and a 101-char line (E501), turning main's test job red and
failing every open PR against it. Ruff --fix reordered the block
(interscript_ml classifies third-party, grouping with pandas); the long
preds-write line split. Unblocks main and the correction PRs.
