fix(carousel): use viewOnceMessageV2 wrapper with messageContextInfo

Switch carousel from direct interactiveMessage to viewOnceMessageV2
wrapper (field 55), confirmed by Z-API as the stable approach for
WhatsApp Web rendering from non-Cloud API accounts.

Key changes:
- Wrap carousel in viewOnceMessageV2 > message > interactiveMessage
  (V1 caused error 479, direct interactiveMessage didn't render on Web)
- Add messageContextInfo with deviceListMetadata and version 2 for
  multi-device rendering compatibility
- Update all helper functions (getButtonType, isCarouselMessage,
  isCatalogMessage, isListNativeFlow, getButtonArgs) to check V2 path
- Update per-device and biz node debug logging for V2 detection
