新增Service方法xUnit集成测试（≥15个用例），更新ServiceFactory支持MachineLatestTag/CollectAnalysis仓库

- ServiceFactory: 新增NewLatestTagRepo/NewCollectAnalysisRepo工厂方法，更新CreateMachineService传参
- DashboardServiceTests: 新增GetProgramRank/GetProgramDistribution的4个测试（无数据+有数据）
- MachineServiceTests: 新增GetLatestTags/GetCollectRecords的3个验证测试
- ProductionServiceTests: 新增GetMachineSummary/GetMachineList/GetWorkerSummary/GetWorkerList/GetProgramSummary/GetProgramList的8个测试
- 修复2个预存测试断言：DashboardService状态值not_installed、CollectAddressService删除抛异常
