feat(pool,ui,trace): 号池按页配额刷新、配额倒计时、Trace 全量候选与 UI 用语统一

- 号池管理支持按当前页 Key 刷新配额，后端 refresh-quota 接口支持 key_ids 参数筛选
- 配额进度条 tooltip 展示重置倒计时，前端解析后端重置时间并实时倒计时
- Provider 选择器在无号池提供商时禁用，切换/刷新后保持选中状态对齐
- 启停账号后立即更新调度标签并刷新列表
- Trace 监控展示全量候选记录，不再过滤 available/unused 状态
- 请求时间线号池节点与 Provider 节点去重
- 全局 UI 用语统一：已停用/已禁用 -> 停用/禁用
- 导航菜单调整模型管理与号池管理顺序
