Add 'use client' to all registered component entry points

RSC auto-classification: files without 'use client' are registered as
Server Components via registerServerComponent(). All existing
components are Client Components (hooks, Redux, Router, event
handlers), so they need the directive to preserve current behavior.

Entry points (7 ror_components/ files):
- App.jsx, NavigationBarApp.jsx, RouterApp.client.jsx,
  RouterApp.server.jsx (SSR wrapper, NOT a Server Component),
  SimpleCommentScreen.jsx, Footer.jsx, RescriptShow.jsx

Pack entry files (2):
- stores-registration.js, stimulus-bundle.js

Per docs/oss/migrating/rsc-preparing-app.md Step 5 and
docs/pro/react-server-components/create-without-ssr.md:52.
Matches Justin's PR 723 final state exactly.
