Summary: The KE handshake already derived the TLS-exporter session keys but threw them away, leaving a client no way to sign NTPv4 requests or verify responses. Return them from the handshake so the upcoming NTS NTPv4 client can use them. They are derived with the same exporter inputs as the server, so both ends agree.
