fix: give the launcher a mark for each state

The pill inverts on hover, so one mark could never work: filled dark it
vanished on the dark hover background, filled light it would vanish on the
accent pill at rest. Both halves of that shipped, one after the other.

Removing the hover rule did not help either, because the GTK theme paints its
own hover shade on the button node underneath. Declining to set a background
does not leave the pill alone, it leaves that shade in charge.

So the mark moves out of the image module and into CSS, where a
background-image can be swapped per state: dark on the accent pill at rest,
light on the dark pill hovered, with the hover background set explicitly
rather than left to the theme. install.sh generates both tints from one source
file, so they cannot drift apart in shape.

That makes the launcher a custom module, since an image module's path is read
once and CSS cannot reach inside it. Its format is a single space for the
usual reason: an empty one draws no widget at all.

install.sh also removes the file the old image module left behind. The prune
only clears dangling symlinks, and that one was written as a real file, so
nothing had been removing it.
