toggle "force focus style"

### This is a Feature suggestion

Having a checkbox (like the "Use text input") to force the focus style on the button would make adjusting the pallet for the focus style easier. Currently, the focus needs to be manually applied either vie the dev tools or by clicking/tabbing the button after each change

Look for the UI controls in the frontend code, likely in a component that handles settings like 'Use text input'. Add a checkbox to toggle a 'force focus style' state. Update the button styling logic to apply focus styles when this checkbox is checked, making it easier to preview focus styles during palette adjustments.
