Drives OptionsMenu:drawPanel() with a mod-loaded Strings catalog and
checks the translated text reaches Font.draw for a cart-original row
(label and its display value), a port-added row's label, and CANCEL,
plus a vanilla no-mod case proving the fallback is unchanged. Reverting
src/ui/gen2/OptionsMenu.lua to its pre-fix content fails 4 of the 9
checks, reproducing the reported bug exactly.
