The GUI's color table, barscale, and north arrow comboboxes load their thumbnail previews from $GISBASE/docs/html/, a runtime dependency of the GUI on the legacy HTML documentation tree, which is being phased
out (noticed in the #7719 review discussion).

This moves the runtime copies to $GISBASE/gui/images/, next to the GUI's other image assets: both build systems generate them there regardless of the documentation options, and the GUI reads them from there. The documentation trees keep their own copies for the manual pages, now consistently generated only when documentation is built.

Implemented with AI assistance (Claude Fable).
