User pointed out the auto-derived panel was title-only; the legacy
panels rendered a small icon in front. Legacy used a URL path (next
Image). The registry-driven path has structured `IconRef` values
(iconify / svg / lazy component) declared on `def.presentation.icon`.
- PanelWrapper's `icon` prop now accepts `string | React.ReactNode`.
String → next/image (legacy URL behavior). Node → rendered as-is.
- ParametricInspector resolves `def.presentation.icon` to a node:
iconify → `<Icon icon="lucide:fence" />`, svg → inline svg, component
→ Suspense + lazy.
Kind-owned custom panels (slab/ceiling) keep their existing legacy
URL icons since they pass `<PanelWrapper>` themselves — no change
needed there.
