"""提现现金账本校验(admin ledger-check)测试:两本物理隔离的账各自对账。

历史盲区:`withdraw_ledger_check` 曾拿全部提现单去和**普通现金流水**(cash_transaction)比对,
而 source=invite_cash 的提现单流水其实在 invite_cash_transaction 表,导致每笔邀请提现单都被
误报「缺扣款/缺退款流水」。这里用真实提现 API 造单 + before/after 差值断言锁定修复:
  1) 邀请提现单不再污染普通现金账的缺流水计数;
  2) 邀请账户已被纳入对账(能抓到它自己的缺流水);
  3) 普通现金账的原有对账未被改坏。

conftest 的库是 session 级共享、测试间不清,故一律用 before/after 差值,只反映本用例造的数据。
