feat(truapi)!: payment requests by id through PaymentPlatform

[filvecchiato]

payment.request and payment.statusSubscribe follow a caller-chosen 32-byte id, as the SDK does. Stacked on #1229.

• AlreadyExists for a reused id, PartiallyClaimed as a status
• Hosts serve both through PaymentPlatform; natively set_payment_callbacks and notify_payment_status
• A product needs a signed-in session to pay or follow a payment

Breaking: the payment request and status wire shapes change.

Part of #1178.
