feat(draw): wire compare card image loading + register the template (T-319)

The drawing card now loads any <image> hrefs its SVG references into ui.Images before painting (loadDrawingImages, decoder injectable for tests) — the renderer and the lightbox both paint through the resolver, so a compare card shows real images and zooms. main registers the `compare` template with a workspace path resolver. A drawing with no images is unaffected. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
