`contractorOps.history.rateBackfill.apply`

Save agreement-derived hourly rate snapshots for explicitly selected imported timesheets after reviewing the preview. Supply each history row id and expectedRevision plus idempotencyKey. Rechecks the agreement and source row atomically; a changed, split-rate or ambiguous week fails without saving any row. Does not mark paid, prepare, approve or send a payout.
