Owls are traced SVGs: six new poses, WebP cutouts gone

The five existing poses come from the c-trace set and six new ones are
hand-traced in the same style: thinking, reading, timekeeper, arguing,
coach and sleepy. Each file is 13 to 21 kB and replaces the 26 glossy
WebP cutouts. The avatar crops the full pose with CSS instead of
shipping separate bust files. The offline precache picks up the poses
that the offline pages show.
