hoteas bd20af0c89 refactor(db): 增强测试事务支持和保存点管理
- 在 HoTimeDB 中新增测试事务功能,允许在测试模式下使用事务进行操作
- 实现 BeginTestTx 和 RollbackTestTx 方法,支持测试事务的开启和回滚
- 在 Action 方法中集成保存点管理,确保在测试模式下的嵌套事务处理
- 更新 README.md,添加 API 测试框架的相关说明,提升文档完整性

// 如果 action 返回 true 则提交事务;返回 false 则回滚
// 测试模式下(testTx != nil),使用 SAVEPOINT 代替真事务,确保嵌套事务不会绕过外层测试事务
