fix: add biz node injection and quality_control for carousel WhatsApp Web rendering

- Add interactive message detection helpers (getButtonType, isCarouselMessage, etc.)
- Inject biz node with interactive/native_flow for non-carousel interactive messages
- Inject biz + quality_control with decision_id for carousel messages
- Skip bot node for native_flow/carousel/catalog (breaks Web rendering)
- Force device-identity inclusion for carousel messages
- Append deferred biz/bot/quality_control nodes after device-identity and tctoken
- Store tctoken under both LID and PN for reliable lookup
