fix: use completeRegistration for incomplete OTP setup in login flow

- LoginPage: call completeRegistration instead of verifyOTP when qrCodeURL exists
- This ensures otp_verified is set to true for users completing OTP setup
- Backend: reorder maxUsers check to allow existing incomplete users to continue
- Backend: return OTP info when login with incomplete OTP setup
