Answering did not open the app: ending the CallKit call immediately (to free the mic)
made iOS cancel the app launch before it foregrounded. Keep the call ACTIVE on answer
— fulfilling an active-call answer is what foregrounds/unlocks the app — and fire the
answerCall event so the WebView joins. didActivate stays a no-op (don't fight WebKit's
mic). The CallKit call is ended later when the WebView call ends.
