feat(pool): 引入多维评分调度策略与账号状态检测

- 新增 multi_score 调度模式，支持 LRU/延迟/健康度/剩余额度多维加权评分
- 新增调度预设维度系统（free_team_first, quota_balanced, recent_refresh, single_account），支持有序对象列表配置格式并兼容旧字符串列表
- 新增 account_state 模块，统一账号封禁/受限检测逻辑，替代分散在 routes 中的判断代码
- 新增 health_cache 模块和 latency 采样（redis_ops.record_latency / batch_get_latency_avgs）
- RequestDispatcher 返回 ttfb_ms，PoolManager.on_request_success 记录延迟样本
- 前端：PoolConfigDialog 替换为 PoolSchedulingDialog，支持预设维度可视化配置；号池管理页增加调度模式标签与账号异常 Badge 显示
- 提取前端 accountBlock 工具函数，ProviderDetailDrawer 复用统一判断
- scheduling_dimensions 增加 account_state 和 latency 维度评估
- 补充 account_state、health_cache、multi_score 策略、preset 维度、redis latency 等测试
