test(cockpit 外围): 修复全量测试 5 个既有失败

全部为上游 7df9a87「优化报警管理」改实现未同步测试所致，非执行票 12
引入（票 12 对这 5 个失败相关文件零改动，已逐文件核实）。

- WaterSupplyDeviceServiceImplTest(2)：实现已把 abnormalReason 从
  alarm.warningType 改为固定文案「设备报警」（7df9a87 删除 warningType
  用法），两处断言仍期望旧值「供水压力超限」→ 更新为当前契约。
- AlarmClearServiceTest(1)：remainingCauseSummary 已统一为固定摘要
  「监测报警」，断言仍期望旧的具体 warningType「流量异常」→ 更新。
- AlarmReviewAttachmentServiceTest(2)：按维护者裁定删除整个测试类。
  该类断言的「内容嗅探/伪造扩展名拦截」是生产代码从未实现的策略，
  且非空文件会先在测试环境触发 NPE（ZksyConfig.getUploadPath() 未
  配置），测试既不反映现行契约也无法在单测环境表达之。

验证：全量 8 模块 Tests run: 414, Failures: 0, Errors: 0（BUILD SUCCESS）。
