Subject: [PATCH] fix(carousel): remove root header + messageVersion to match
 ckptw

Compare with ckptw's working carousel implementation:
1. Remove root header from interactiveMessage - ckptw does NOT set
   a header on the root, only on individual cards. The root header
   was incorrectly believed to prevent error 479.
2. Remove messageVersion from carouselMessage - ckptw doesn't set it.

Structure now matches ckptw exactly:
  viewOnceMessage > message > {
    messageContextInfo,
    interactiveMessage: {
      body, footer,
      carouselMessage: { cards }  // no messageVersion
      // no header at root level
    }
  }
