fix(messages): detect interactive messages inside viewOnceMessage wrapper

The getButtonType function was not detecting interactive messages
when wrapped inside viewOnceMessage (the modern nativeFlowMessage format).

This fix adds detection for:
- viewOnceMessage > interactiveMessage
- viewOnceMessage > listMessage
- viewOnceMessage > buttonsMessage

When enableInteractiveMessages is true, the 'biz' node will now be
correctly injected for messages using the viewOnceMessage wrapper.
