fix(json-render-ui): restore shadow-root theming and scrollbars

[dvcolomban]

Summary

• move the light and dark scheme classes onto a display-contents ancestor so Wind3 descendant selectors apply inside the renderer shadow root
• keep the renderer shell transparent while preserving semantic text colors and native color-scheme behavior
• bundle the design-system scrollbar stylesheet and reserve a stable scrollbar gutter
• allow the shared shadow CSS builder to merge ordered hand-authored stylesheets
• add a Storybook fixture that mounts the shipped dock renderer in a real shadow root

Pull request overview

Restores correct theming behavior for the @devframes/json-render-ui dock renderer when mounted inside a real shadow root (matching Wind3 descendant-selector semantics), while also improving scrollbar styling and the shared shadow-CSS build pipeline.

Changes:

• Move .dark/.light + color-scheme onto a display: contents ancestor so Wind3 dark-variant selectors apply inside the renderer shadow root.
• Add bundled scrollbar styling + stable scrollbar gutter for the renderer scroll root.
• Extend design/build-shadow-css.ts to accept and merge multiple ordered hand-authored stylesheets, updating callers accordingly and adding a Storybook fixture that mounts the shipped dock renderer in a shadow root.
