liuwenxin e7e47d88bc feat(settlement): 月度结算快照生成与审批锁定,调整单(补发/扣减)与审批联动
- settlement_service:generate(确认回款口径 #8 策略点=有效台账行按回款日
  归月、经理聚合 #12 暂口径基数不含经理个人户、月结 uk 一行一月、草稿/
  驳回可重生成、已审定/待审 400)→ submit(审批开关分流,关=自动通过即
  锁定、开=待财务复核)→ approval_service.act 扩 order_type=2/3 钩子
  (通过=mark_locked/调整单生效;驳回=回草稿/作废,延迟导入防循环)
- 锁定拦截:回款新增写路径校验回款月已审定 400(比需求「提示」取硬,
  一期安全侧;M2 已核算禁改防线先于其生效)
- 调整单:新建(TZ 单号,开关分流自动通过留痕/走审批)+ 列表
- schemas settlement:金额 Decimal 声明(str 声明遇 Decimal 入参拒绝)
- 测试 6 例:生成回填/无记录 400/已审定重生成 400/关自动锁定/锁定后回款
  禁改/开两节点流转至锁定(finance→leader)
