三处重复的 StartsWith/EndsWith 字符串解析（GetInterests / InitInterestDate / SwapEodPositionService EOD平仓后结息）收口为 TradeExtendJson 计算属性： - [JsonIgnore] 保证 ExtendJson 序列化字节不变； - InitInterestDate 原写法在 InterestCalcMode 为显式 null 时会 NRE， 收口后与其他两处 null-安全语义对齐（缺省=算头算尾，实际不可达，属性缺省 11）。 EQD-6968 三判定之一的"算不算尾"至此单点可查。 验证：内存套件 102/102 全绿（GLMS20260817Fr007 23 + Cache 7 + CloseInterest/ InterestScenario/TailSnapshot/EntrySemantics 72）
