fix: add workaround for hds-core cookie consent

HDS 6.0.2 ships cookieConsent.ts but not cookieConsent.js
at the path required by hds-react, causing build failures.
Add fix-hds-shim script that creates a compatible shim
from cookieConsent.css.
The shim uses an ES module-shaped export and avoids
Node built-ins so webpack/browser bundling works.

+### `pnpm fix-hds-shim`
+
+Workaround for a packaging issue in `hds-core@6.x`: generates a missing `cookieConsent.js` file that `hds-react` expects but the package does not ship.
+This is run automatically by `pnpm dev` and `pnpm build`. Run it manually if you encounter a `MODULE_NOT_FOUND` error for `hds-core/lib/components/cookie-consent/cookieConsent` after installing dependencies.
+Can be removed once HDS publishes a fixed release.
