死参数收口（另一半）： - SwapDealService.GetInterests 删 needPrice/grossPrice（体内零消费，2026-08 验证）； InitSwapDealInterest.needPrice 同为死参数一并删 - SwapEodPositionService.CalcSwapInterests 签名+转发同步；两个 EOD 生产调用点 (SaveAutoEodInterestPosition/SaveEodInterestPositionCopy) 重排实参； CalcEodPostCloseSettleInterests/GetIntradayUnwindInterests 委托同步 - 14 个测试文件 ~44 处直调点机械更新（8 处 override 签名 + 36 处调用实参） - 注意：EOD 编排链(DealInterests→Save*家族)的 grossPrice(期初不含费价)有真实用途，保留未动 新增钉子：CalcEodPostCloseSettleInterests 工厂→接缝参数映射测试—— CalcSwapInterestsCapture 捕获 stub 断言 EodPostCloseSettle 的完整转发契约 （posi=平仓后剩余/closePosi=平掉额/恒1/settment:false/orginPv 等 11 项）。 该段位置转发含三个相邻同型 decimal，编译器不查错位，此测试兜底。 验证：定向 241 测试通过（含 T0/T1 Excel 验证期望值、EntrySemantics 精确值钉子—— 任何 decimal 错位即红）；全量 903=145失败/746通过/12跳过，与基线逐位一致。
