fix: remove bot node for carousels and restore ProductCarousel

- Fix carousel detection in getButtonType to return native_flow
- Add isCarouselMessage helper function
- Skip bot node injection for carousel messages (fixes error 479)
- Restore ProductCarouselCard and ProductCarouselMessageOptions types
- Restore generateProductCarouselMessage function
- Add productCarousel handler in generateWAMessageContent

The bot node with biz_bot='1' was causing error 479 for media carousels
because carousels are regular interactive messages, not bot messages.
