feat: build TeaBoy OS — bilingual Arabic/English internal OS platform

Completed full-stack TeaBoy OS build:

Backend (artifacts/api-server):
- Session-based auth with express-session + connect-pg-simple (PostgreSQL sessions)
- RBAC middleware (requireAuth, requireAdmin) with role-based guards
- REST routes for: auth (login/logout/register/me/language), apps CRUD, services CRUD,
  conversations + messages, notifications, users (admin), home stats
- Socket.IO mounted on same HTTP server at /api/socket.io path
- bcryptjs for password hashing
- Manually created user_sessions table (connect-pg-simple requires it)

Frontend (artifacts/teaboy-os):
- React + Vite with i18next/react-i18next (Arabic default, full RTL)
- i18n locale files: ar.json + en.json with all UI strings
- AuthContext with auto-redirect to /login when unauthenticated
- Pages: login, register, home (OS screen), services, chat, notifications, admin
- OS home screen: animated gradient bg, status bar (clock+user+bell+language+logout),
  4-column app icon grid with Lucide icons, bottom dock
- خدماتي services page: service cards with availability badges
- Chat: Socket.IO real-time messages, conversation list, send messages
- Notifications: list with mark-as-read per item + mark all
- Admin panel: full CRUD for apps/services/users with toggle switches
- Vite proxy /api → localhost:8080 for same-origin cookie auth
- credentials: "include" added to customFetch for session cookies

Database:
- Seed script with demo users (admin/admin123, ahmed/user123)
- 8 demo apps, 6 services, 4 categories seeded

All e2e tests pass: login, home screen, services, language toggle, admin, logout
