feat(wm-dma): #59 DMA分区计量与漏损分析
- 新增 wm-dma 模块 - Entity: DmaZone, DmaMeter, DmaFlowRecord, DmaLeakageAnalysis, WaterBalance - Mapper + Service + Controller（18个端点） - DMA分区管理: 分区层级定义(CRUD) + 区域划分 + 关联设备 + 树形结构 - 分区计量: 各分区进出水量汇总 + 最小夜间流量(MNF)分析 + 流量趋势 - 漏损分析: 产销差计算 + 漏损率评估 + 趋势分析 + 报警 - 水平衡表: 供水量/售水量/漏损量平衡分析 + IWA组成 - DDL: dma_ddl.sql - 单元测试: 5个Service测试类（25+测试用例）
