feat(iot): B1 新建 viewsh-module-iot-rule Maven 模块骨架

- 新增 viewsh-module-iot-rule/pom.xml（仅依赖 iot-api + iot-core + Aviator 5.3.3 + mybatis/redis starter）
- 新增 package-info.java / ModuleSmokeTest.java / spring.factories 占位
- viewsh-module-iot/pom.xml <modules> 新增 rule（core 之后、server 之前）
- viewsh-module-iot-server/pom.xml 新增 rule 依赖（core 之后、业务组件之前）
- Known Pitfalls 落地：
  ⚠️ 评审 A3：依赖方向 rule → core → api，严禁反向（dependency:tree 验证）
  ⚠️ 评审 R6：server 对 rule 的依赖按项目一贯顺序插入
  ⚠️ Aviator 5.3.3 首次引入，rule 模块 pom 内显式声明 version

Acceptance Criteria 全 8 项通过（见任务卡 Notes §8.2026-04-23 执行记录）
