AP2 PaymentReceipt Verifier & HNP Guardrail

Verifies an AP2 v0.2 PaymentReceipt against its signed Intent/Cart/Payment mandate chain, and applies the Human-Not-Present (HNP) autonomy guardrail: amount, category, mandate age, cart freshness. Runtime/post-trade: art-01 validates the mandate before the buy; ART-62 verifies the receipt after, applying HNP gating (AP2 v0.2 new primitive, FIDO Alliance Apr 2026).
