Phase 1 #18: PostgreSQL + TDengine 完整 DDL 建表脚本

- 15+张核心表: sys_*(部门/用户/角色/菜单/日志/字典/通知/文件) - iot_*: 设备模型/设备实例/设备影子/设备事件/站点(PostGIS空间坐标) - rev_*: 用水户/水价阶梯/水表档案/水表操作日志/抄表/账单/缴费/报装 - production: alert_rule(报警规则)/alert_event(报警事件)/dispatch_command(调度)/duty(值班)/patrol(巡检)/water_quality(水质) - TDengine: iot_telemetry超级表(6类设备子表)+事件表+小时聚合 - 种子数据: admin管理员/5个角色/6个片区/基础字典
