    network: Fix wifi icon loading
    
    GTK4 changes how icons are loaded - only icons that are
    set up to follow icon theme paths are recolored. The way
    the network panel loaded icons wasn't compatible with this,
    causing icons to stay dark in dark mode.
    
    This commit adjusts the gresource so that icons are
    in `$RESOURCE_BASE_PATH/icons/scalable/actions`. Since
    GTK knows how to handle that automatically, we can
    simply use `icon-name` instead of loading a full
    icon path.
