Draw each building's icon glyph over its footprint fill in place of the text
identity glyph (REQ-UI-WORLD-ICON): production buildings, HQ, and defence
stations. GameWorldView pre-renders each type's icon (chip background stripped)
in a white and a dark variant and picks the contrasting one by fill luminance;
belts, splitters, and tunnels are excluded and keep their tile/text rendering.
Wired into operational buildings, construction sites (icon + progress), stations
(previously letterless), and the builder/blueprint ghost. Update the requirement
wording from "white glyph" to a contrasting ink.
