refactor(frontend): replace React Router BFF with Wouter SPA

Remove React Router 7 SSR/BFF architecture (server-side loaders,
actions, sessions, remix-auth) and replace with a client-side SPA
using Wouter for routing and cookie-based JWT auth.

- Replace reactRouter() Vite plugin with @vitejs/plugin-react
- Add index.html + app/main.tsx as SPA entry points
- Add Wouter routing with auth guards (ProtectedRoute/PublicOnlyRoute)
- Add client-side auth (app/auth.ts) and useAuth hook
- Migrate all route files to app/pages/ with client-side data fetching
- Update NavigateLink and GolfPlayAppGaming to use Wouter Link
- Remove .server/, routes/, root.tsx, react-router.config.ts
- Clean up tsconfig.json (remove .react-router references)
