feat(wm-data-engine): #4 数据汇聚引擎完整实现

DE-01 数据采集: 实时流(Kafka)+批量采集, WebSocket推送
DE-02 数据接入: RESTful API/数据库直连/文件接入/数据源管理
DE-03 数据存储: TDengine时序+PostgreSQL关系+MinIO对象
DE-04 数据集成: 全量/增量同步, 数据合并聚合, 血缘追踪

新增实体: DataSource/CollectTask/CollectRecord/StorageConfig/QualityRule/SyncTask/DataLineage
新增服务: DataCollectService/DataIngestService/DataStorageService/DataIntegrationService/DataGovernanceService
新增控制器: DataCollectController/DataIngestController/DataStorageController/DataIntegrationController/DataGovernanceController
新增配置: KafkaConfig/WebSocketConfig/MyBatisPlusConfig
新增DDL: V1__data_engine.sql (12张业务表)
新增测试: 5个Service测试类覆盖核心业务逻辑
