DingTalk Device Flow authorization.

Implements the same 3-step registration flow as dingtalk-openclaw-connector:
  1. POST /app/registration/init   → get nonce
  2. POST /app/registration/begin  → get device_code + verification_uri_complete
  3. POST /app/registration/poll   → poll until SUCCESS → get client_id + client_secret

The verification_uri_complete is rendered as a QR code in the terminal so the
user can scan it with DingTalk to authorize, yielding AppKey + AppSecret
automatically.
