fix(web): stop the sidebar update icon from rendering clipped

The update pill is a 32px inline-grid with overflow hidden. Its hidden
nowrap label shares the single grid cell, so the track grew to the label
width and the icon was centred in that oversized track, then clipped to a
half circle. Pin the track to the pill width and let both items shrink.

Also shrink the sidebar logo from 220px to 200px.
