fix: normalize and rewrite node.attributes and moduleOverlay.props in applyAssetRewrites

- Add rewriteAttributes helper for DOM-native node attributes
- Update rewriteFragment to also rewrite node.attributes and node.moduleOverlay.props
- Update applyImport.test.ts to check node.attributes instead of node.props.htmlAttributes
- Update applyImport.test.ts to check both node.attributes and node.moduleOverlay.props for src
- Fixes remaining test failures in hybrid-dom-native-nodes branch
