feat(pool): 号池额度主动探测、封禁自动清除、调度硬优先级与前端重构

- 新增 PoolQuotaProbeScheduler，按 probing_interval_minutes 主动探测静默 Key 额度
- pool_advanced 增加 probing_enabled / auto_remove_banned_keys 配置项
- error_handler 和 quota_service 支持封禁 Key 自动删除及缓存清理
- multi_score 策略从加权混合重构为硬优先级排序，引入 mutex_group 互斥组
- 指纹注入从 handler 层下移至 ClaudeCode envelope 层
- OAuth 批量导入支持 concurrency 并发参数
- 前端号池管理拆分高级设置/账号批量/代理设置为独立组件
- 号池总览接口精简，仅返回已启用调度的 Provider
