- 将平仓条件判断从 UnwindDate 改为 EventDate - 移除不再使用的 priorClosePositionIds 变量 - 统一使用 NormalizeEventUnwindDate 替代 NormalizeIncomeUnwindDate - 在多个平仓方法中添加 NormalizeEventUnwindDate 调用 - 更新流程事件的 EventDate 和 UnwindDate 字段 - 修改单元测试以验证按 EventDate 分桶的逻辑 - 在前端控制器中将 unwindDate 设置为 valueDate - 添加 maxdate 属性到平仓日期选择器 - 实现事件日期与平仓日期的双向同步功能 - 更新利息列表获取接口使用统一日期参数
