Include Device-Level Status Code in Chatbot Default Node Output

NetBrain's chatbot default node output currently surfaces only intent-level Msg/Status Code information. When an intent's status code level changes to device level, chatbot flows built against the prior intent-level output no longer display any result. This enhancement would update the chatbot default node output to include both intent-level and device-level status codes, or default to device-level status code, and would apply equivalent handling to existing chatbot definitions that reference only intent-level status codes. Customers would benefit from consistent chatbot behavior across product versions, avoiding silent result gaps when underlying status code levels change.
