Embedded interviews respect your theme and background, even in voice mode
Fixes
- The appearance controls in embedded interviews now behave correctly. The light and dark toggle works and a participant's choice sticks for their session, and in voice conversations (which are always dark) the toggle is hidden instead of showing a control that does nothing.
- Voice conversations now keep the custom background color set on an embed instead of forcing the background to black, so the conversation matches the page it lives in.
