Only userId 1105261382487539712 and 1116631120763437056 can see the
scheduling tab. Other users see only assets + mileage modules.
- Add userId to frontend AuthState.user type
- App.tsx conditionally includes scheduling module based on user ID
- Backend already returns userId in auth exchange response
