fix(aiot): 回退告警 API 到 Service 后端,修复截图 URL 端点

告警问题:
- 告警数据存储在 FastAPI Service 的 alert_platform.db 中
- 之前错误地切换到 wvpRequestClient(WVP 后端的 wvp_ai_alert 表)
- 回退到 requestClient + /aiot/alarm/alert/* 路径恢复数据

截图问题:
- /snap/image 代理端点在 Redis+DB 都无缓存时返回 404
- 回退到 /snap 端点,利用其 Accept: image/* 自动 302 重定向逻辑
- 保留 force 参数支持手动刷新截图
