Quote or reserve a sponsor/lobby card paid action. Requires API key with purchase:prepare scope. Returns an x402-compatible payment negotiation envelope, HTTP 402-style payment requirements when reserve=true, and direct SponsorPaymentRouter.paySponsorBlock(...) settlement requirements. Pure quotes do not hold inventory; reserve=true creates a short-TTL payment-required sponsor reservation.
