Automatic execution of chatbot NIT nodes with a single candidate device

Chatbot automation currently requires a user to manually click through each Network Intent Task node during a troubleshooting flow, even in cases where only one candidate device is available for that step. This adds unnecessary time and manual effort to what should be a streamlined automated process. This enhancement would introduce a setting that allows a specified NIT node to execute automatically when it has only one alternative device, removing the need for manual confirmation at that step. Customers running chatbot-driven troubleshooting flows would benefit from faster resolution times and a more consistent end-to-end automated experience.
