"""T6.2 仪表盘端点测试。

覆盖目标
--------

- ``GET /api/stats/dashboard`` 鉴权 (401 / 200)
- 鉴权通过后返回的 payload 形状稳定
- 空库时:
  - summary 全 0
  - by_status / by_source / by_service_version 完整 0 填充
  - trends.today = 1 点, 7d = 7 点, 30d = 30 点, 全部按日期升序
  - generated_at 是合法 ISO8601 UTC
- 真实写入订单后:
  - summary.total_orders / total_revenue_cents / orders_7d / 趋势 累加正确
  - 收入口径 = 排除 pending 与 refunded
  - 窗口边界 (今日 / 7d / 30d) 切分正确
  - 趋势 0 填充 : 范围内无订单的日也返回 0 点
- 业务隔离 : 订单 DB 与 admin DB 是分开的, admin_users 计数独立
