feat(frontend): 结果/实验/策略/数据页迁移 shadcn 与新 Chart API

[变更性质]
四个业务标签页与数据集卡片迁移 shadcn 组件，图表消费切换到
layerchart 长格式 API，功能与数据语义不变。

[新增功能]
结果页权益曲线（策略权益/现金/基准，基准可缺省）与回撤曲线（desc
面积）改由 Chart.svelte data/series 渲染；实验记录页多回测归一对比
曲线改为快速长格式行构造。空数据行允许 undefined 列（基准缺口），
Chart data 类型放宽 [key:string]: string|number|undefined。

[实现方案]
RunsPage：查看入口改 shadcn Button（href 语义保留 hash 路由），
对比图数据由 compareOption（echarts option）化为 compare。
ProjectResultsTab：图表开关、日志折叠用 Button；equityData/
drawdownData $derived 计算峰值回撤。ProjectStrategyTab：快照输入、
冲突/AI/版本操作迁移 Button/Input。ProjectDataTab 与 DatasetCard：
shadcn 组件 + 保留 banner error/warn/info、retry-row 等 legacy class，
"使用相同请求重新获取"重试入口与 onRecreated 逻辑不变，配套
datasetCardRetry/datasetCardWarnings/projectDataTabRecreated 回归
测试。resultsAccounting.test.ts：layerchart 在 jsdom 挂载约 3 秒，
suite 全量下易撞默认 5s 超时，首测提高至 20s。

[影响范围]
npm run check 0 error、58 tests 全绿、npm run build 通过；真浏览器
375/768/1440 图表页零溢出（artifacts/ui-shadcn 截图与探针 JSON）。
