If status=ACCEPTED is processed before Meta's connect webhook, the call
is already in_progress when accept_outbound_call runs, and the previous
guard dropped the SDP answer — leaving the browser without the data it
needs to complete the WebRTC handshake. Gate on a stored sdp_answer
instead of in_progress so out-of-order delivery still persists and
broadcasts the answer (and connect retries stay idempotent).
