feat(monitor): admin channel monitor MVP with SSRF protection and batch aggregation
新增 admin「渠道监控」模块(参考 BingZi-233/check-cx),独立于现有 Channel 体系。
admin 配置 + 后台定时调用上游 LLM chat completions 健康检查 + 所有登录用户只读可见。
后端:
- ent: channel_monitor + channel_monitor_history(AES-256-GCM 加密 api_key)
- service 按职责拆分:service/aggregator/validate/checker/runner/ssrf
- provider strategy map 替代 switch(openai/anthropic/gemini)
- repository batch 聚合(ListLatestForMonitorIDs + ComputeAvailabilityForMonitors)消除 N+1
- runner: ticker(5s) + pond worker pool(5) + inFlight 防并发 + TrySubmit 防雪崩
+ 凌晨 3 点 cron 清理 30 天历史
- SSRF 防护:强制 https + 私网/loopback/云元数据 IP 拒绝(127/8、10/8、172.16/12、
192.168/16、169.254/16、100.64/10、::1、fc00::/7、fe80::/10)+ DialContext
在 socket 层防 DNS rebinding
- API key sanitize:擦除 url.Error 与上游响应 body 中的 sk-/sk-ant-/AIza/JWT 模式
- APIKeyDecryptFailed 标志位 + 单 monitor 路径检测,避免空 key 调用上游
handler:
- admin: CRUD + 手动触发 + 历史接口(api_key 脱敏)
- user: 只读列表 + 状态详情(去除 api_key/endpoint)
- ParseChannelMonitorID 共用 + dto.ChannelMonitorExtraModelStatus 共用
前端:
- 路由 /admin/channels/{pricing,monitor} + /monitor(用户只读)
- AppSidebar 父项 expandOnly 支持
- ChannelMonitorView 拆为 8 个子组件 + ChannelStatusView 拆出 detail dialog
- composables/useChannelMonitorFormat + constants/channelMonitor 共享
- i18n monitorCommon namespace 消除 admin/user 两 view 重复
