Turn the automatic renewal (autoRenew) of the transaction's parent title on/off (row action 'Pause/Resume renewal'). Only allowed on recurring titles (MONTHLY/QUARTERLY/SEMIANNUAL/ANNUAL) — one-time/installment titles are rejected (400). It does not recreate transactions: with false the next settlement stops triggering the rolling renewal; with true the rolling runs again on the next settlement. Returns the transaction detail with the title's autoRenew reflected.
