fix: correct badge item detection by checking classname prefix

Badge item_names already start with 'badge_' (e.g. badge_citycpa3),
so checking for badge_<item_name>_icon.png produces a double prefix
(badge_badge_citycpa3_icon.png). Now uses item_name.startsWith('badge_')
instead, which correctly identifies badge items without depending on
icon files existing in the directory.
