fix(combat): restore retail combat bar controls

Resolve authored StringInfo labels from local.dat, port gmCombatUI's runtime option captions and checkbox widgets, and bind horizontal scrollbar media by retail structural roles so the green power jewel is a thumb instead of a tiled track. Persist the three combat options and make Auto Target govern target acquisition.
