fix(web): kb document chunk total size

[shuqinzhao]

Summary by Sourcery

在知识库文档详情和召回测试结果中，跟踪并展示后端返回的文档分片（chunks）总数。

New Features:

• 为召回测试结果暴露一个总数属性，用于显示与当前已加载列表无关的整体分片数量。

Bug Fixes:

• 确保召回结果计数反映的是后端报告的文档分片总数，而不仅仅是当前已加载页的数量。

Enhancements:

• 将分页元数据（总数）从文档详情中存储并传递到召回测试结果视图。

Original summary in English

Summary by Sourcery

Track and display the total number of document chunks returned by the backend in knowledge base document details and recall test results.

New Features:

• Expose a total count prop for recall test results to show the overall number of chunks independent of the currently loaded list.

Bug Fixes:

• Ensure the recall result count reflects the backend-reported total number of document chunks instead of just the currently loaded page.

Enhancements:

• Store and propagate pagination metadata (total count) from document details to the recall test results view.

将后端返回的知识库文档分块总数传递到 RecallTestResult 视图中，这样结果数量就能反映完整总数，而不仅仅是当前已加载页面的数量。

按文件划分的改动

变更	详情	文件
在召回测试结果中增加一个可选的总数并从文档详情的分块分页响应中串联传递。	扩展 RecallTestResult 的 props，增加一个可选的 total 字段，并在组件签名中默认设为 0。 更新 RecallTestResult 中的结果计数显示逻辑，当提供 total 时优先使用 total，否则回退到 data.length。 在 DocumentDetails 中增加 total state，用于跟踪来自分页元数据的分块总数。 在获取文档详情时，从 response.page.total 设置 total，当该字段缺失时默认设为 0。 将追踪到的 total 从 DocumentDetails 传递到 RecallTestResult，使 UI 显示完整的分块总数。	web/src/views/KnowledgeBase/components/RecallTestResult.tsx web/src/views/KnowledgeBase/[knowledgeBaseId]/DocumentDetails.tsx

Propagate the backend-reported total number of knowledge base document chunks into the RecallTestResult view so the result count reflects the full total instead of just the currently loaded page.

File-Level Changes

Change	Details	Files
Add an optional total count to recall test results and wire it from the document details chunk pagination response.	Extend RecallTestResult props with an optional total field and default it to 0 in the component signature. Update the result count display in RecallTestResult to prefer the total value when provided, falling back to data.length. Add total state in DocumentDetails to track the total number of chunks from the page metadata. Set total from response.page.total when fetching document details, defaulting to 0 when missing. Pass the tracked total down from DocumentDetails to RecallTestResult so the UI shows the full chunk count.	web/src/views/KnowledgeBase/components/RecallTestResult.tsx web/src/views/KnowledgeBase/[knowledgeBaseId]/DocumentDetails.tsx

Hey - 我在这里给出一些整体反馈：

• 在 RecallTestResult 中，建议使用空值合并运算符（total ?? data.length）来代替 total || data.length，这样在 total 合法地为 0 时，就不会被 data.length 覆盖。

给 AI 代理的提示

Please address the comments from this code review:

## Overall Comments
- In `RecallTestResult`, consider using nullish coalescing (`total ?? data.length`) instead of `total || data.length` so that a legitimate total of `0` is not overridden by `data.length`.
