regarding chat model selection in the NC assistant same as for text2image etc

[JosefAschauer]

Describe the feature you'd like to request

I understand that you closed #177 but there might be a solution to satisfy everyones needs.

Wouldn't it be a good idea to put an option into the AI admin settings whether to let the user choose the AI model or stick with what the admin decided, in other words whether to use the general form (used ie in text2image, which allows model picking) or the custom form currently in place?

Best,
Josef

Describe the solution you'd like

I think its clear from the description and the description in Issue #177

Describe alternatives you've considered

unfortunatelly there is none. Users complain and ask me to change the model used back and forth. They do not understand why they can pick the LLM of their choice in other tabs of the NC assistant but not in chat
