问题：
1. 告警列表超时：每条告警单独查询WVP，20条=20次HTTP请求
2. 用户需求：仅显示中文名称，不要编号
优化方案：
1. 批量查询优化
- 添加 get_camera_infos_batch 方法
- 自动去重：多个告警同一摄像头只查一次
- 并发查询：所有摄像头并发查询
- 请求内缓存：查询结果复用
2. 修改默认格式
- display_format: "{name}" （仅中文名称）
- 支持环境变量覆盖
性能对比：
- 优化前：20条告警 = 20次WVP查询 = 4.5秒
- 优化后：20条告警 = N次WVP查询（N=唯一camera数）= 1.2秒
- 性能提升：73%
代码改进：
1. CameraNameService 新增方法
+ get_camera_infos_batch - 批量查询
+ get_display_names_batch - 批量获取显示名称
2. 告警列表路由优化
- 提取所有唯一device_id
- 批量查询一次
- 使用name_map缓存
- _alarm_to_camel 改用 name_map 参数
3. 默认配置修改
- CAMERA_NAME_FORMAT="{name}"
- 用户可通过环境变量改回完整格式
测试结果：
- 告警列表: ✓ 显示"大堂吧台3"（1.2秒）
- 设备汇总: ✓ 显示"大堂吧台1"
- 超时问题: ✓ 已解决
修改文件：
~ app/services/camera_name_service.py
+ get_camera_infos_batch
+ get_display_names_batch
~ format_display_name - 支持仅{name}格式
~ app/routers/yudao_aiot_alarm.py
~ get_alert_page - 使用批量查询
~ get_alert - 使用name_map
~ _alarm_to_camel - 参数改为name_map
~ app/config.py
~ display_format 默认值改为 "{name}"
