"""提现对账(#4 孤儿单兜底)。

扫描超过 N 分钟仍 pending 的提现单,逐单查微信归一化:
  - 微信 SUCCESS               → 置 success
  - 微信失败/取消/关闭/无此单    → 退回现金 + 置 failed
  - WAIT_USER_CONFIRM(久未确认)→ 撤销 + 退款
防止"扣了款但转账没发起/没确认"的单永久锁住用户余额。

用法(建议 cron / systemd timer 每 5~10 分钟跑一次):
    python -m scripts.reconcile_withdraws            # 默认处理 >15 分钟的 pending
    python -m scripts.reconcile_withdraws 30         # 处理 >30 分钟的 pending
