feat: 添加回路名称字段并实现元数据缓存查询
在 RCU 事件处理中新增回路名称(loop_name)字段,用于标识具体设备回路。 - 在 rcu_action_events 表中添加 loop_name 字段 - 新增项目元数据缓存模块,每日从 temporary_project 表刷新房间与回路信息 - 处理消息时,根据 device_id、dev_addr 等字段查询缓存获取回路名称 - 若缓存未命中,则根据设备类型规则生成兜底名称 - 更新环境变量、文档及测试用例以适配新功能

- **Error Handling**: Redis List (`error_queue`) for failed messages + Retry mechanism

- **Output**: PostgreSQL Table (`rcu_action_events`)

## Features
|
||||
- **Loop Name Enrichment**: Enriches event data with `loop_name` by matching `device_id` and `dev_addr` against metadata cached from `temporary_project` tables (refreshed daily).

## Configuration (Environment Variables)
|
||||
The project is configured via `.env`. Key variables:
|

- **Kafka**: `KAFKA_BROKERS`, `KAFKA_TOPIC`, `KAFKA_SASL_USERNAME`, `KAFKA_SASL_PASSWORD`
