Apply Baseline Corrections to Regression Transformations

Copy baseline corrections onto regression transformations.

Looks up regression transformations created against the comparison version (isRegression: true, correctedJSON IS NULL), finds the matching baseline transformation by referenceID, and copies the baseline's correctedJSON onto the regression row via the same code path used by POST /v3/events/{eventID}/feedback. The applied corrections are immediately scored against the regression output, populating the confusion-matrix metrics used by function-review and function-version-compare.

Works for every function type that produces correctable transformations, including extract on both the vision and OCR paths. (Previously the vision path silently dropped is_regression during the original regression run, so no rows matched the predicate — that has been fixed.)

Returns counts plus the list of event KSUIDs whose underlying regression transformation received a correction. Errors (e.g. baseline transformation missing for a given referenceID) are returned per-row in the errors map, keyed by event KSUID, rather than aborting the whole call.
