r'''清掉 _build/ 里剩下的 5 处明文管理密码。

形状：
    _build/check_web.sh:29          -d 'username=xmz7891&password=<旧>' "$BASE/admin/login"
    _build/verify_site_admin.sh:38  同上
    _build/split_site_admin2.py:10  注释里
    _build/split_site_admin2.py:22  ADMIN_PASS = "<旧>"
    _build/test_response_headers.py:28  PASS = "<旧>"

改法：
  * shell 脚本改成从环境变量读：${RELAY_ADMIN_PASSWORD:?请先设置}
  * Python 改成 os.environ.get("RELAY_ADMIN_PASSWORD")
  * 注释里把密码删掉，改成说明怎么取
