The Prefer header is used by NUT-20 for long-polling support but was being blocked by the CORS middleware. Add it to the allowed headers list for both auth and non-auth configurations.
Drop internal payment/settlement tracking and correlation ID embedding which were unused complexity. Add webhook subscription rotation to prevent hitting Strike's 50-subscription limit, and validate webhook URLs require HTTPS.
Add cdk-agicash crate that wraps Strike backend to restrict melts to invoices from a configured Square merchant. Validates by matching invoice description and timestamp against synced Square payments (polling + webhook + on-demand sync). Rejected invoices return PaymentNotAllowed (20739) with user-facing message.
