feat(tenant): 租户-项目两级架构 Phase 2 — IoT + Ops 业务迁移

DO 迁移 (15个 TenantBaseDO → ProjectBaseDO):
- IoT: IotDeviceDO
- Ops 核心: OpsOrderDO, OpsOrderEventDO, OpsOrderDispatchDO, OpsOrderQueueDO,
  OpsBusAreaDO, OpsAreaDeviceRelationDO, OpsDeviceTrajectoryDO
- Ops 保洁: OpsOrderCleanExtDO, OpsCleanerStatusDO, OpsCleanerPerformanceMonthlyDO,
  OpsInspectionRecordDO, OpsInspectionRecordItemDO
- Ops 安保: OpsOrderSecurityExtDO, OpsAreaSecurityUserDO

IoT 适配:
- IotDeviceRespDTO 新增 projectId 字段
- IotDeviceMessage 新增 projectId 字段
- IotDeviceMessageServiceImpl.appendDeviceMessage() 设置 projectId
- IotCleanRuleMessageHandler 嵌套 ProjectUtils.execute() 设置项目上下文

缓存改造:
- ProjectRedisCacheManager extends TenantRedisCacheManager，追加 :projectId 后缀
- ViewshTenantAutoConfiguration 替换为 ProjectRedisCacheManager

SQL 迁移脚本 (sql/mysql/project/):
- 01-create-tables.sql: system_project + system_user_project 建表
- 02-default-data.sql: 默认项目 + 用户关联回填
- 03-alter-business-tables.sql: 15 张表添加 project_id (NULL → 回填 → NOT NULL → 索引)
- 04-index-audit.sql: 现有索引审计 + project_id 补充建议
- 99-rollback.sql: 完整回滚方案

附带修复:
- fix(ops): UserDispatchStatusServiceImpl 添加缺失的 KEY_PREFIX 常量
