fix(frontend) : fix z-index overlay hiding drawers and add pathPrefix config

Lower the white overlay div from z-50 to z-30 so it still masks scrolling
content but no longer covers drawers/modals teleported to body.
Add components pathPrefix: false to resolve auto-imported components
without folder prefix.
