hjhan 55284fb76b refactor(margin): 抽出独立 Margin 限界上下文,移除 PrepayLeg 错误继承
- 新建 YLErp.Modules.SwapModule.Margin:MarginBalance / MarginLeg / IMarginResolver(Cash/Credit/Guarantee)

- MarginLeg 不继承 IInterestLegStrategy,与利息腿完全解耦(保证金是客户存款/担保,非互换腿)

- 删除 PrepayLeg,工厂不再注册 mode 5/6 预付金

- 预付金用例迁入 MarginLegTest,旧 InterestLegStrategyTest 改为断言预付金已非利息腿
