Outbound IN_PROGRESS no longer claims "They answered" — the backend can
flip in_progress before the contact actually picks up (Twilio agent-join
flow), so the label "Call in progress" stands on its own. Outbound
no_answer now reads "Contact didn't pick up" instead of the inbound
"Missed call / No answer" framing, and outbound ringing shows
"Calling…" instead of "Not answered yet".
