feat(debug): re-enable remote controls for MUI mirrors

device-ui now accepts injected input (virtual LVGL pointer + group-attached
keypad bridged from the InputBroker), so the view-only treatment goes away:
the D-pad navigates MUI widgets, taps forward panel coordinates, and the
keyboard types. The mirror_view_only string stays for the future
capability-flag path.
