  * 测试错误处理(Prisma错误、权限验证)

增强现有测试:
- 字段池管理器测试 - 新增6个测试
  * 测试字段池同步重试机制
  * 测试OptionCleaningIssue枚举
  * 测试边界情况处理

- 模板验证器测试 - 新增10个测试
  * 测试批量验证功能(validateMultipleTemplateIds)
  * 测试模板字段获取(getTemplateWithFields)
  * 测试性能指标(验证时间<100ms)
  * 测试批量查询优化

测试覆盖:
- 总计72个测试用例全部通过
- 覆盖任务1-8的核心功能
- 包含单元测试、集成测试、性能测试
