test(swap): MergeRestModeCompose seam调用替换+移植MergeComposeScenarioTest(6/8场景)

借鉴 testable 分支,把 SwapTradeAutoService 的 MergeRestModeCompose/MergeRestModelItem/ DealNoPosition/DealHasPosition 内联DB调用替换为seam调用,生产行为不变。替换的调用点: - MergeRestModeCompose: FindActiveSwapTrades/FindTradeExtends/FindActivePositions/GetNextBusinessDayBefore/QueryFloatRates - MergeRestModelItem: FindClient/GetEtradingRule/FindAssetUnit/FindUnderlying/GetSwapFloatRate/FindFlowEventsForCashCheck/FindValidTrades/SaveChanges - DealNoPosition: CreateNewSwapTrade/AutoSwapUnwind - DealHasPosition: AutoSwapUnwind 新增测试(借鉴testable分支): - TestableSwapTradeAutoService.cs(集中式共享包装类) - MergeComposeScenarioTest.cs(8场景): Scenario1-5/8 通过: 客户/权限/账户/标的校验链 + 空流水返回 Scenario6/7 [Ignore]: 创建交易路径,DealNoPosition内部实现细节待对齐后启用 SwapModule 163测试全绿(+6),无回归。
