feat(iot): Wave 5 Round 1 — B8/B13 规则链缓存 + AlarmHistory 时序 DAO

Browse Source 
B8 规则链全量缓存 + Redis Pub/Sub + 版本拉模式兜底：
- CompiledRuleChainFactory：IotRuleChainGraphVO→CompiledRuleChain
- RuleChainCache（@PostConstruct loadAll + evict + reload + B48 钩子）
  · TenantUtils.executeIgnore 跨租户全量加载；TenantUtils.execute 逐租户切换
  · ConcurrentHashMap.compute 保证 reload 串行（避免并发 DB 查询）
  · 超 500 条规则链打 WARN 日志
- RuleChainCacheListener：Redis Pub/Sub 订阅 iot:rule:cache:evict，收到后 evict+reload
- RuleChainVersionChecker：5 分钟拉模式兜底，version drift 时 reload + metric
- RuleChainCacheConfiguration：@EnableScheduling + RedisMessageListenerContainer
- IotRuleChainMapper 新增 selectAllEnabledTenantIds()（跨租户查询）
- IotRuleChainServiceImpl.updateRuleChain 末尾发布 Pub/Sub 驱逐事件
- 5 单元测试全绿（含 version drift 检测 + 容量告警）

B13 AlarmHistory 时序表 DAO 双实现：
- AlarmHistoryDO（时序对象：ts/device/severity/ack/clear/archived/eventType 等）
- IotTsDbAlarmHistoryDao 接口（insert/queryByAlarmRecord/queryLatestByDevice）
- CtsdbAlarmHistoryDaoImpl（CTSDB/InfluxDB 协议，@ConditionalOnProperty）
- TdengineAlarmHistoryDaoImpl（TDengine JDBC，@ConditionalOnProperty）
- IotAlarmHistoryService（协调 TSDB 写；异步 @Async；写失败不影响主流程）
- TsDbAutoConfiguration 注册 IotAlarmHistoryService
- 5 单元测试全绿（含 TSDB 失败降级 + 异步写验证）

测试总计：rule 模块 164/164 ✓，server 模块 B13 5/5 ✓
