fix(carousel): restore viewOnceMessage wrapper for Web/Desktop rendering

WhatsApp Web/Desktop requires interactiveMessage to be wrapped inside
viewOnceMessage.message to render carousels fully. Without the wrapper,
only the header/body text is shown. The previous error 479 was caused by
missing messageVersion and empty messageParamsJson in cards, not by the
viewOnceMessage wrapper itself. Those card fixes are preserved.
