feat(swap): 添加公司行为现金分红按登记日权益数量计算功能

Browse Source 
- 新增 CalcBondPayment 方法支持传入公司行为权益数量参数
- 在 SwapEodPositionService 中识别现金分红类型的公司行为持仓
- 修改 CopyEodPosition 和 UpdateEodPosition 方法传递公司行为前的数量信息
- 更新 SaveCurrentEodInitalPosi 方法支持公司行为数量计算
- 在 BondPaymentService 中实现公司行为现金分红按登记日权益数量计算逻辑
- 添加单元测试验证公司行为现金分红使用除权前数量的计算功能
