Re-scoring seam — re-runs scoring for a binding and reports how many rows were
scored. Wraps the MLModelInferenceProcessor batch path (via the score
runner) in production; tests inject a fake returning a canned count. Keeps the
MaintenanceEngine decoupled from the scoring runner's storage/sidecar wiring.
