cameraModes

Camera modes available in the call UI, in preference order. The first entry is the initial mode. When only one mode is listed the flip-camera control is hidden; an empty list disables camera capture (the video toggle is hidden and the camera is never requested). Remote video and screen sharing remain available unless videoMediaEnabled is false. Modes unsupported on the current device are silently dropped (COMPOSITE is dropped on devices without multi-cam). SCREEN_SHARE is always ignored — screen sharing is controlled separately. Defaults to [SELFIE, WORLD, COMPOSITE].
