wire spec-driven auth: remove VITE_AUTH_BASE_URL, reorder providers

- main.jsx: remove VITE_AUTH_BASE_URL env var; add AppContent that
  reads authConfig from useAppContext() and passes to AuthProvider;
  reorder: AppProvider -> AuthProvider -> BrowserRouter
- sync react-openapi: AuthConfig type, extractAuthConfig, loading fix
- sync react-auth: authConfig prop, config-driven paths, server logout
