Load the whole config again under Hyprland 0.57

Hyprland 0.57 refuses a bind on a bare modifier and an empty input:scroll_method. The switcher's Super-release commit now binds Super_L and Super_R, which also brings back every bind below it in keybinds.lua. An empty scroll method is left unwritten, so libinput still picks per device.
