Summary

Add functionality to the rotary controller interface that allows users to toggle between different feed rate display formats by pressing the feed rate display. This includes switching between mm/min & M/min and in/min & Ft/min pairs on the digital readout (DRO).

Details

• On each click, switch between:
  • Metric mode: mm/min and M/min
  • Imperial mode: in/min and Ft/min
• Update the displayed labels and values immediately on toggle.
• Preserve the selected mode across screen updates and application state.
• Ensure toggle is smooth and does not interfere with encoder rotation inputs.
• Matches the more typical feed rate units
