test: re-pin the #316 baselines to the review-fix source

Pixels are untouched — the r1/r2 review fixes change migration data flow,
not rendering; every scenario hash stays byte-identical to the frames of the
reviewed CI run. Only the source fingerprint moves to match the fixed tree.

Issue: #316

Release: v1.68.0-beta.4
