feat: enhance table layout and interaction across various components

- Introduced a new `WorkspaceTable` component for consistent table styling and behavior.
- Updated `BacktestPage`, `DatasetPage`, and `DataPreparationPage` to utilize the new `WorkspaceTable`.
- Implemented compact row heights and ellipsis for long text in table cells.
- Added validation for online field queries to ensure at least one filter is provided.
- Enhanced error handling and user feedback for invalid input scenarios.
- Improved pagination controls with dynamic page size options.
- Documented table display specifications in `ui-tables.md`.
- Added tests to verify table layout, interaction, and error handling.

+# 实现首页信息模块
+Type: task
+Status: ready-for-agent
+Implementation: completed
+
+按 ../spec.md 实现后台存储、读取/刷新/解读接口、Semi 首页模块和配置改名。不得报名、接受协议、提交 Alpha 或执行任务。
+
+## Comments
+- 开始核验实际账户响应及当前代码。
+
+- 完成后端账户隔离快照、可比较日度排名历史、分页读取、独立错误及手动 AI 解读缓存；来源/共享连接变化失效，生成期间变化拒绝覆盖旧解读。
+- 完成 Semi 首页信息卡片与比赛侧栏、Lucide 图标、模型名称及无障碍说明调整，保留 model/description_model 字段。
+- 真实账户只读核验：消息首批 10 条、next_offset=10；参赛列表 6 条；活动按分页读取 21 条且当前均已结束；核验协议 1 个文本块、约 1.3 万字，比赛排名字段存在；顾问 dailyOsmosisRank=0 按未知展示。
+- 验证：新增首页后端测试 17 项通过；既有看板、Description 与 AI 测试 121 项通过；现有 AI/侧栏浏览器回归 6 项通过；Ruff、类型检查、生产构建、git diff --check 通过。
+- 隔离浏览器验证：手动生成与原文引用、重开不自动调用、翻页、模型变更待更新、失败保留旧内容、桌面/390px/深色；窄屏模块宽度与 scrollWidth 均为 366px，侧栏稳定后 x=0、width=390px。
+- 临时 SQLite 完整迁移到 0016，并回退本次迁移到 0015 后重新升级通过。未变更生产数据库。
+- AI 使用确定性模拟模型验证，未调用真实供应商；生产构建仍有既存 lottie eval 和大包体积提示。未提交或部署。

+# 统一表格规范与回测 500 排查
+
+Type: task
+Status: resolved
+
+按 Alpha 管理统一数据目录、字段目录、数据准备的 Semi Table 行高、Tab、分页、状态 Tag、单元格截断和紧凑筛选区；在线查询改为第二个 Tab，明确输入并提交条件才请求。用户授权将规范固定为项目文档。回测 500 先复现并核对失败接口，再修复验证。
+
+## Comments
+
+- 开始处理；工作区干净。
+
+- Semi 2.103.0 Table、Tabs、Tag 文档已核对；新建 WorkspaceTable 统一 40px 行高、截断、表体滚动和底部分页。三个目录及准备选择器已接入，状态使用 Tag，筛选栏上下 padding 4px。
+- 在线目录移到第二个卡片 Tab；默认及仅输入时不查询，重置清空结果。前后端均要求额外查询条件。
+- 用户提供运行列表 URL 和 ResponseValidationError / extra_forbidden 日志。使用含额外来源字段的持久化记录复现同类响应错误；新增 SourceOutput 仅投影当前字段，输入 Source 保持严格校验，不恢复旧输入字段或进行快照转换。
+
+## Answer
+
+本地修改完成。项目展示规范见 docs/ui-tables.md，AGENTS.md 与 README 已接入入口。
+验证：后端 Ruff 通过；回测与准备模块 pytest 41 项通过，新增复现测试修复前失败、修复后通过；前端构建通过（保留既有打包体积及 lottie eval 提示）；Playwright 9 项通过，最后列宽与 Tag 调整后另复核 2 项通过。浏览器实测 40px 行高、长名称不溢出、桌面及 900px 窄屏底栏固定，截图已检查。
+仅本地代码与模拟上游验证，未部署或修改线上数据；部署后需要确认线上运行列表恢复。

 新增或调整 Semi UI 组件用法（属性、布局、对齐、状态展示、交互、主题样式），排查组件专属行为或进行版本迁移时，优先使用 `semi-mcp` 核对文档与示例。纯业务逻辑修改不触发此查询。
 
 - 先从项目依赖及锁文件确认实际版本，发现当前可用的 Semi MCP 工具，再按该版本调用 `get_semi_document`；示例被折叠时使用 `get_semi_code_block`。

 2. Base URL 是后端能够访问的 API 根地址，例如 `https://供应商域名/v1`，是否带 `/v1` 以供应商说明为准；无需拼接 `/chat/completions` 或 `/responses`。容器中的 `localhost` 指容器自身。
 3. 保存配置不会发起模型请求。点击“测试连接”后，系统用少量合成文本和无副作用工具分别测试回答、流式输出、工具往返；测试可能按供应商规则计费。

+| 页面结构 | 可选 Tab → 筛选及操作栏 → 表格 → 底部分页 |
+| Tab | Semi `Tabs type="card"`，浅灰栏底色，`tabPaneMotion={false}`；单视图无需空 Tab |
+| 表头、数据行 | 40px 高，单元格上下 8px、左右 16px；正文 13px，内容高不超过 23px（含边框后整行 40px） |
+| 筛选及操作栏 | 每行上下 padding 4px、左右 12px，margin 0，控件间距 8px；更多条件按需展开 |
+| 表体 | 列宽明确、固定表格布局；宽表仅在表体内横向滚动，主列表纵向占满剩余空间 |
+| 分页 | 表格外底栏，左侧总数及更新时间，右侧页码和每页条数；主列表支持 25／50／100 条 |
+
+主列表使用 `WorkspaceTable fill`、`scroll.y="100%"`，父级 flex 链保持 `min-height: 0`。Tab 的内容及 motion overlay 同样参与高度约束，使表头和底栏可见、表体独立滚动。弹窗中的预览表格可使用限定高度。
+
+## 单元格与交互
+
+- 每列提供合适宽度，长名称、ID、描述保持单行省略。使用 Semi `ellipsis` 和共用 `.workspace-cell` 边界；完整内容可通过标题提示或详情查看。
+- 状态使用小尺寸、浅色 Semi `Tag`，文字明确表达状态，颜色仅作辅助：成功绿色、进行中蓝色、等待灰色、警告橙色、失败红色。缺失值显示“未提供”。
+- 名称入口使用 borderless Button，宽度限定在单元格内。行操作使用 `.workspace-cell-actions`，不复用筛选栏样式；按钮、Tag 和任何子元素均不得侵入相邻列。
+- 多选使用 Semi `rowSelection` 和稳定的业务键；表头全选只作用于当前页，跨页保留选择，切换数据范围清空选择。批量操作展示选择数量，空选择时禁用。
+- 筛选或每页条数改变时回到第一页。服务端分页场景由后端排序，保留受控分页；只有接口支持的排序条件才展示为可用。
+- 字段目录先“本地同步”，后“worldquant接口”。在线字段查询只有填写关键词、数据集、类型或数值筛选条件并点击查询后才执行；范围默认值本身不触发查询。重置及切换范围清空在线结果和勾选。
+
+## 验证
+
+使用长名称、长描述、状态、多页数据及空结果检查。浏览器回归需验证 40px 行高、单元格内截断、Tab 切换、分页及选择保留；在桌面与窄视口检查表体滚动和底栏可达。在线目录检查首次打开、仅输入未提交及重置均不会调用字段查询接口。
