test(swap): GLMS-20260105-0007分红精度差异golden红灯(复现0.36差异)

Browse Source 
用真实测试库数据录制golden,回放复现0.36精度差异:
- 互换前 PosiDividendSum=-90400,互换支付-400
- 期望 PosiDividendSum=-90000,实际=-89999.64,差异0.36
- 回放断言失败(红灯坐实bug)

根因:UpdateEodPosition cs:1635从头重算PosiDividendSum
(Round(全程,2)-已实现),与CopyEodPosition逐天递增
(每天Round(增量,2)累积)产生舍入误差。

录制方法Record_FromRealDB标[Ignore],手动跑生成golden。
回放方法Replay_VerifyPrecisionDiff进CI,当前红灯(期望=-90000,实际=-89999.64)。
