Fix Reanimated unresolved imports under webpack

web/reanimatedWebUtilsShim.js

+ * Replacement for react-native-reanimated's js-reanimated/webUtils.web.js,
+ * wired up via a webpack alias in webpack.config.js.
+ *
+ * The original file declares ES module exports but populates them with bare
+ * CommonJS `require()` calls wrapped in try/catch. Webpack parses the file as
+ * ESM and therefore leaves those `require`s untouched, so in the browser they
+ * throw ReferenceError, the try/catch swallows it, and createReactDOMStyle &
+ * co. stay undefined. That silently disables reanimated's DOM update path and
+ * _updatePropsJS later crashes with "Cannot convert undefined or null to
+ * object" on Object.keys(component.props). Importing the same react-native-web
+ * internals statically fixes the resolution.
