fix(EQD-7004): 补全分红登记日口径修复的多次付息累计测试与Trace日志

Browse Source 
原修复 9df39491 仅覆盖单次登记日(4/3)的两个单点修复，本次补全 EQD-7004 的完整验证与排查手段：

- 测试 GLMS20260105_0006 新增 4 个场景：5 期 reg_date 过滤口径各自命中正确子集；五期票息累计=5x36160=180800；auto 实现归0后下次登记日重新累加；4 期挂账累计读 144640

- 分红读取关键链路加 Debug 级日志(生产可关)：BondPaymentService.GetBondPayments(reg_date 过滤区间+命中条数)、SwapDealService.GetPreEodPositionByDate(EOD 定位+回退)、GetPreEodDividendSum(取EOD日期+PosiDividendSum)、方案C 平仓预览/收益结算两处 DividendIn 赋值

实跑 dotnet test 全 GREEN(6/6)。任务编号 EQD-7004。
