[Enhancement] Add option to "Reset" settings in Monarch Controller

[jtmuller5]

It would be nice to have a button to reset the settings in the Monarch Controller to their default starting values (ex. 1.0 text scale factor, 100% scale, Material Light Theme, etc). I think this will become more useful as additional settings, like time zone or environment, are added.

This is a great idea! It shouldn't be too difficult to implement.
