feat(window-switcher): mark desktops with waybar's icons

The card's desktop line showed the workspace number. waybar draws the same
eight desktops as CSS background images keyed by number, because its
format-icons takes text rather than paths; those names now live in the
Windows singleton and are resolved through the active icon theme, so a
theme switch follows the drawer and the bar and the switcher agree. A named
workspace, or one past eight, falls back to its number, and so does an icon
the active theme cannot resolve.
