✨ feat(*): 添加 PCB 检测记录的 CSV 持久化存储功能

* 新增 CsvBoardRecordRepository 实现按日期分卷的 CSV 记录存储
* 新增 RecordPersistenceModels 定义板件检测记录数据结构
* 在 WorkflowHostedService 中集成检测完成后的记录持久化
* 更新 MainWindowViewModel 支持记录查询与异常标记
* 更新 AppStateStore 添加记录存储相关状态管理
* 新增 DashboardPage UI 元素展示记录存储状态
* 更新 SystemSettingViewModel 与 appConfig 添加存储路径配置
* 注册 TimeProvider 与 IBoardRecordRepository 到 DI 容器
* 新增 CsvBoardRecordRepositoryTests 与 MainWindowViewModelTests
* 配置 Release 模式 portable PDB 并在发布时自动移除
