Slice SP.3 (workplans/SECTION_PREVIEW_WORKPLAN.md).

Replaces the 26 hand-drawn resources/images/*_xsect.svg thumbnails with outlines sampled from the engine, so the palette tiles and the live preview can never disagree, the icons follow the theme foreground, and shapes that never got artwork (BASKETHANDLE, SEMICIRCULAR, CUSTOM, FORCE_MAIN, DUMMY) get a correct tile for free.

Icons are drawn at a nominal unit depth with representative widths (see nominalGeomsFor()), not at the link's real dimensions — a palette tile shows what the shape is, and rendering a 0.15 m pipe and a 3 m box culvert to their true relative scale would make most tiles unreadable.
