test(swap): 新增 ClosePercent 口径A产品契约测试,防止平仓比例被改为占剩余口径

新增前后端回归测试,锁定产品需求:ClosePercent 永远是占期初名义本金的比例。后端 CPC_001~010 装配测试验证 SwapDealService 真实执行 ToRemainingClosePercent/ToOriginalClosePercent 转换;前端 16 项接线测试验证 unwindSwapTrade.js 使用 NotionalValue 作为分母且 postData 携带 notionalValue 字段。测试背景:c9071a4e 曾将 ClosePercent 改为占剩余口径导致回归但现有测试全通过,本测试通过源码装配与契约验证弥补该缺口。

/// 平仓比例口径A(占期初名义本金)产品契约测试
/// ================================================================================
/// 产品需求(不可违背):
/// ClosePercent 永远是"占期初名义本金(NotionalValue)的比例",即口径A。
/// 例:期初本金 5000 万,首次平 35%ClosePercent=0.35),剩余 3250 万。
/// 第二次想平掉剩余的 50%ClosePercent 应 = 1625万/5000万 = 0.325(占期初),
/// 而非 0.50(占剩余)。
///
/// 前后端协作约定:
/// - 前端(unwindSwapTrade.js):ClosePercent 始终以 NotionalValue 为分母计算/显示
/// - 前端传给后端:ClosePercent 为口径A
/// - 后端入口(SwapUnwind/ApplySwapTrade):ToRemainingClosePercent 将 A→B 供内部计算
/// - 后端落库(SaveSwapDealInternal):ToOriginalClosePercent 将 B→A 还原存储
/// - 后端 InitUnwind 默认值:CalcDefaultInitClosePercent = PosiNotionalValue/NotionalValue(口径A
///
/// 本测试守护的回归场景(c9071a4e 曾犯的错误):
/// 1. 前端把 oriClosePercent 硬编码为 1(应为 PosiNotionalValue/NotionalValue
/// 2. 前端把 CloseNotionalValue 分母从 NotionalValue 改为 PosiNotionalValue
/// 3. 前端把 ClosePercent 分母从 NotionalValue 改为 PosiNotionalValue
/// 4. 前端把 getInterestList 的 notionalValue/posiNotionalValue 参数去掉
/// 5. 前端把 calcCloseQtyByPercent 从 SwapCalc.calcCloseQtyByOriginalPercent 改为直接乘
/// 6. 后端 InitUnwind 默认 ClosePercent 改为 1 而非剩余比例
///
/// 与既有测试的关系:
/// - ApplySwapTradeClosePercentBugTest:测 A→B 转换函数正确性(函数级)
/// - InitUnwindDefaultClosePercentTest:测默认值函数正确性(函数级)
/// - 本测试:测完整多步场景的口径A契约(场景级),补齐"装配测试"盲区
