Signing scheme

Every payload (inbound + outbound) is signed with HMAC-SHA256(secret, timestamp + '.' + nonce + '.' + body). Timestamp must be within a 5-minute window; nonce must be unique across the last 24 hours. Failed verification returns RFC 7807 401 signature_invalid with a human-readable detail.
