test(draw): cover the 2.9.0 drawing-card additions to clear the coverage floor

The drawing-card feature batch (icon/image/compare/graph/d2 cards, --stdin, tool resolution) added widget + wiring code that dipped total coverage under the 95% floor — surfaced by `make release` (push-check skips coverage). Cover the gaps: ProblemsController.refresh, every SVG shape-type bbox + the style vocabulary, _spawnD2 via a real /bin/cat, the icon-show bus path + error branches, and quad/arc/close marker paths.
