test(swap): 为债券TRS期间结算自动互换10场景补单测 + SaveAutoSwapDeal接缝可测化

- 新增 BondTrsAutoSwapScenarioTest:覆盖测试场景/测试场景-0702复测两页
  10个自动互换场景(含付息日历登记日2/28→支付日3/2、资金发生日3/3/3/4)、
  部分平仓后按登记日持仓数量计算(剩余60%为54240)、同日多腿合并、
  分红支付日偏移、无结算观察日不得凭空产生互换等,共11条断言全绿。
- SaveAutoSwapDeal 改为走 AddClientCash/AddSwapEvent/PersistFlowEvent 接缝
  (默认实现与重构前行为一致,零行为变更);UpdateInitalPostion 由 private
  改 protected virtual;GetPreDealDate 改 virtual,便于无DB单测。
