// Action: register an outbound webhook subscriber.
//
// After registration, Keysat will POST signed JSON bodies to the URL when
// relevant events fire (license.issued, license.revoked, machine.activated,
// machine.deactivated, invoice.settled, etc.). Signatures use HMAC-SHA256
// over the body, carried in the `X-Keysat-Signature` header as
// `sha256=<hex>` — same shape as BTCPay's outbound hooks.
