feat: 添加 HA 管理面板功能

- config_flow.py: 新增人员管理步骤（async_step_manage/list/create）
  支持在 HA 配置 -> 选项 中查看人员列表、创建和删除
- __init__.py: 新增 3 个 WebSocket API 命令（list/create/delete）
  前端可通过 HA WebSocket 直接调用
- blueprints/face_detection_automation.yaml: 自动化蓝图
  支持人脸检测/搜索 + 通知推送
- manifest.json: 版本号 2.2.0

用户现可通过 HA 界面对人员进行可视化管理
