"""福利页(coin_cash)提现档位规则测试(7-9提现ui对齐)。

规则(2026-07-09 拍板):
  - 档位 0.1/0.3(新人,历史一次性,免广告)+ 0.5(日3次)/10/20(日1次)。
  - 计次口径"发起就算":当天创建的单不论最终状态(含被拒)都占名额;新人档任何状态都算用过。
  - 常规三档每天只能选一个;新人档不参与该互斥,两个新人档同天可各提一次。
  - invite_cash 无档位概念:tiers 为空、下单不走档位闸(邀请页行为不变)。
wxpay 调用全部 monkeypatch;现金余额 DB 直灌(同 test_withdraw.py 套路)。
