Apply an Offer to a subscription PUT

Apply a direct Offer to a subscription. On a pending payment checkout it quotes or replaces the checkout discount and the existing checkout URL remains unchanged. On an active subscription it applies the Offer immediately with its discount phases starting at the next billing cycle; the call is rejected while another applied Offer still has active or upcoming discount phases. Offers with a free trial phase cannot be applied after checkout creation.
