issue doxygen#11549 Leftover variable in CSS (validation and possible logic issue)

- `width: $width` is handled in navtree.js
- css files are not handled by means of `copyResource...` anymore
- handling of the contents of Luminance files is done solely in css files now, so no separate Luminace template files anymore
