refactor(video): 预置 AI 算法改为 SQL 种子数据,移除 @PostConstruct 初始化

原 AiAlgorithmServiceImpl.initPresetAlgorithms() 在 @PostConstruct
里插入 4 条预置算法,带来两个问题:
1. 启动时无登录上下文,MP 自动填充 creator 失效 → 启动失败
2. 算法清单硬编码在 Java 代码,迭代要重编译发布

改为 video.sql 种子数据管理:
- video.sql 的预置算法 INSERT 扩展为 4 条(leave_post / intrusion /
  illegal_parking / vehicle_congestion),参数 schema 与边缘端对齐
- 使用 ON DUPLICATE KEY UPDATE 保证幂等:新库初始化 + 存量库升级
  都走同一条语句,param_schema / description 会被自动校正
- 保留用户侧可修改的字段(is_active / global_params)不被覆盖

代码层:
- 删除 initPresetAlgorithms() 方法与 PRESET_ALGORITHMS 静态 Map
- 删除 SYSTEM_USER 常量
- 删除 @PostConstruct / HashMap 相关 import
- 保留 syncFromEdge() 作为边缘端主动同步的运行时入口
