Allow for more settings to be set via the settings UI

[ryx2]

What problem or use case are you trying to solve?

I would like more customizability from the settings on the localhost UI.

Describe the UX of the solution you'd like

This settings section

Could very easily fit:

max_iterations Everything in the LLMConfig (via a file)

Do you have thoughts on the technical implementation?

In the "advanced settings", have max_iterations be a number input, and then also allow to specify a path to a LLMConfig file.

Describe alternatives you've considered
