test(eod): 为 FR007 入库 UnderlyingId 守卫补纯函数单测

- EodPriceService 抽出纯函数 ResolveUnderlyingIdForCode（行为不变），SyncUnderlyingIdFromCode 调用之，便于无库单测 - 新增 EodPriceUnderlyingIdGuardTest：7 用例全过，覆盖空代码/标的不存在维持原值、已一致不改动、FR007 错行(511160.SH=2173889、159111.SZ=2173890)校正为 2170838、非错配不互相覆盖 - 对应根因：GLMS-20260701 FR007 价格行 UnderlyingId 错挂导致网页查得到/结算查不到
