No matching route for AI steps with buttons

Business problem

When AI routing in a journey uses buttons, the 'no matching route' option is missing. If a user types their own message instead of selecting a button, the chatbot still tries to match the input to an existing path, which often results in repeating the original question and a frustrating user experience.

Desired outcome

The ability to add a 'no matching route' to AI routing steps that contain buttons. This would allow users who don't choose the suggested options to be naturally guided to an alternative path to handle edge cases correctly.
