Fix keybind conflict and wallpaper daemon handling

- Changed suggested keybind from SUPER+W (conflicts with Close window
  in Omarchy) to SUPER ALT+W
- Stop hyprpaper/swaybg before starting mpvpaper so the video wallpaper
  is actually visible
- Restart hyprpaper when toggling motion wallpaper off so the normal
  wallpaper is restored
