Fix SketchyBar workspace indicators not reappearing

The aerospace workspace plugin had two issues preventing workspace
indicators from properly showing/hiding:

1. The script expected workspace number as $1 but update_freq routine
   calls only provide $NAME environment variable. Now extracts from
   either source.

2. Using drawing=off to hide workspaces was unreliable - items wouldn't
   consistently reappear. Now uses width=0 with cleared icon/label
   content to collapse items instead.

Workspaces now properly appear within 2 seconds when windows are
created or moved, without requiring manual sketchybar --update.
