[#DEV-910] Migrate to DataRouter

Each website received following changes:

• Wrapping all elements in:

const router = createBrowserRouter(
  createRoutesFromElements(
    <>
    {...routes}
    </>
  ),
  { basename: import.meta.env.BASE_URL },
)

• Updating <App/> to simply contain:

    <BaseWrapper>
      <RouterProvider router={router} />;
    </BaseWrapper>

or some variation of this, depending on specific case

• index.ts to simply have this:

root.render(<App />);
