"""
一键初始化测试用户 — 打通认证→业务页面的完整链路。

用途：
  在没有租户管理后台的情况下，直接在 test_zqyy_app 中插入必要的
  映射数据，让测试用户能通过 dev-login 登录后正常访问业务页面。

操作内容：
  1. 确保 site_code_mapping 中有真实门店映射
  2. 创建/更新测试用户为 approved 状态
  3. 分配门店角色（user_site_roles）
  4. 创建助教绑定（user_assistant_binding）
  5. 输出可用于测试的 JWT token

使用方式：
  cd C:\\NeoZQYY
  python scripts/ops/init_test_user.py [--openid <openid>] [--role <role_code>] [--reset]

环境要求：
  - 根 .env 中配置 APP_DB_DSN（指向 test_zqyy_app）
  - WX_DEV_MODE=true（dev-login 端点需要）
