HUD: a weapon says what its ammunition label shows; a beam reads its reserve alone

ConstantWeapon names an AmmoType but has no magazine (a crate per AmmoInterval straight from the cargo), so the label printed its unfilled
magazine ("1/N"). Weapon.AmmoReadout owns the label's text, HasMagazine says whether there is a magazine to show, and SchematicDisplay reads it.
