i18n: route hardcoded UI strings through Strings(), auto-size menu boxes, optional metric dex fields

Makes several UI spots reachable for translation mods without forking the
engine. All behavior-neutral for the base game: Strings(x) is the identity
function when no catalog is loaded, and the metric dex fields are opt-in.

- ListMenu: draw the title via Strings() (covers bag/PC/box/fly/move lists)
- Menu / (see follow-up ChoiceBox): grow the box to the widest label so longer
  localized labels don't overflow the frame
- OptionsMenu: wrap toggle values (ON/OFF, SET/SHIFT, WIDE/OG, text speed) and
  the ruleset display name in Strings()
- Schemas: add optional dexEntry.heightM / weightKg
- DexEntryMenu: render metric height/weight when those fields are present,
  otherwise unchanged (ft/in + lb)
