UI/UX 全面改进:22项优化落地(报纸风前端 + 管理后台)

P0 严重问题:
- 采集任务进度反馈:Collection 页新增任务状态跟踪(运行中/完成/失败) + 轮询 ingest 状态
- 积分榜加载态:切换联赛显示 spinner + 禁用 tab 防重复点击
- 数据完整性可操作:问题列表每项加「去修复」按钮,跳转采集页并预填参数
- 面包屑导航:顶部显示 仪表盘 > 当前页

P1 重要问题:
- 侧边栏当前页指示器:1.5px 圆点 → 4px 左侧彩色竖条 + 背景高亮
- Key Ring 重置确认:点击「重置冷却」前弹窗确认
- 预测比赛选择器:只显示未开赛 + 联赛筛选 + 显示可预测数量
- 表格移动端溢出:评估页表格加 overflow-x-auto
- 设置页合并:数据源 + LLM + 系统配置 → 统一「设置」页
- 预测按钮去重:移动端/桌面端合并为一个响应式按钮

P2 体验优化:
- 日志滚动保持:自动滚动仅当用户未向上滚动时
- 评估结果预览:显示「共 N 组」
- ⌘K 命令面板:键盘导航跳转所有管理页面
- 专家意见折叠:默认折叠,可展开(已存在)
- 版本信息:侧边栏底部显示 v1.0
- 积分榜表格:min-w 防止挤压
