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 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
