feat(proxy): 节点状态简化、连接事件记录、可靠性指标与批量删除

- 移除 UNHEALTHY 中间状态，节点状态简化为 ONLINE/OFFLINE
- 新增 proxy_node_events 表记录 tunnel 连接/断开/错误事件
- 新增 failed_requests/dns_failures/stream_errors 可靠性指标（增量累加）
- tunnel 重连改为固定 1s 延迟，移除指数退避逻辑
- resolver/service 改为以 TunnelManager 内存状态判断节点可用性，避免 DB 竞态
- 修正 Claude cache_control 字段格式，使用 ttl 字段控制缓存时长
- 移除前端手动勾选 capability 的 UI，改为从价格配置自动推断
- 新增全局模型批量删除 API，替换前端并行单个删除
