desktops/sway: drop the mpvpaper live wallpaper
mpvpaper rendered a looping video on every output, which makes every frame
full-screen motion. On the sunshine-streamed tablet screen that meant a
constantly saturated encoder and an unusable stream (97% of frames dropped
at 5 Mbps), and on the real outputs it is pointless power draw.
noctalia owns the desktop background again (wallpaper.enabled = true); pick
the image in its wallpaper panel. ~/wallpaper is no longer seeded, but
lockscreen still uses whatever is in it.
