hjhan 946cbbb66d refactor: InterestLeg 改名 FundingLeg(业界标准 Financing Leg)
命名: InterestLeg→FundingLeg, 消除'interest'与通用'利息'歧义。
Funding精确表达'融资成本'(客户付券商的杠杆成本 spread+FR007)。

改名清单:
- IInterestLegStrategy → IFundingLegStrategy
- InterestLegStrategyFactory → FundingLegStrategyFactory
- InterestLegStrategyTest → FundingLegStrategyTest
- 命名空间 InterestLegs → FundingLegs
- 目录 InterestLegs/ → FundingLegs/
- SwapDealService 引用同步更新

验证: 编译0错误, 全量503测试7失败(基线一致)。
