feat(iot): Wave 5 Round 1 — B8/B13 规则链缓存 + AlarmHistory 时序 DAO
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 ✓ Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
