/**
 * 初始化清单「验收」的真实链路脚本：注册 → 申请 → 运营审核 → 积分记账与幂等。
 *
 * 前提：voko-server 已启动（VOKO_API，默认 http://localhost:9201），.env 已配置真实 SMTP；
 *   VOKO_TEST_EMAIL：一个能收信的邮箱，脚本用 plus 地址注册新用户（如 you+voko-xxx@gmail.com）；
 *   VOKO_ADMIN_EMAIL / VOKO_ADMIN_PASSWORD：一个已用 admin:grant 设为管理员的账号。
 * 缺任一项输出 BLOCKED 并以 2 退出，不用替身补绿。
 * 结束时只清理本脚本创建的数据。
