Follow-ups on top of salvaged #13923 (@keifergu):
- Print QR poll dot every 3s instead of every 18s so "Fetching
configuration results..." doesn't look hung.
- On "status=success but no bot_info" from the WeCom query endpoint,
log the full payload at WARNING and tell the user we're falling
back to manual entry (was previously a single opaque line).
- Document in the qr_scan_for_bot_info() docstring that the
work.weixin.qq.com/ai/qc/* endpoints are the admin-console web-UI
flow, not the public developer API, and may change without notice.
Also add keifergu@tencent.com to scripts/release.py AUTHOR_MAP so
release notes attribute the feature correctly.
