模拟盘模块: - 新增模拟盘列表页(List.vue):统计行+富表格(名称/模式/频率/收益/最新净值/状态/操作)+搜索筛选 - 后端加 GET /paper 列表端点(类比 GET /task,带最新净值+收益率) - paper/New 分区富表单(卡式模式选择+频率+撮合时点说明) - paper/Result 重做(收益/年化/回撤/夏普/波动指标卡+净值曲线+归因表+成交明细,净值客户端算指标) 因子模块: - factor/Result 重做(最优ICIR/平均IC/显著数指标卡+彩色IC表+tears报告tab化) - factor/New 重做(因子按类分组多选+标的批量+实时计数) 回测模块: - backtest/Progress 重做(步骤时间线+进度条+实时日志尾3s刷新) - backtest/New 重做(策略/参数/标的区间/基准分区富表单) - backtest/Optimize 重做(结果列头可排序+Top1高亮+按收益默认降序) - History 迁移scoped chip→全局chips.css(DRY清理) 全局:深色主题统一,复用 tokens.css + chips.css
