feat(knowledge): add file upload with text extraction for knowledge base

支持在管理后台知识库页面上传文件（PDF、Word、TXT、Markdown），
自动提取文本内容，管理员预览编辑后保存为知识库文章。

## 后端 (knowledge-service)

- 新增 TextExtractionService：文件文本提取服务
  - PDF 提取：使用 pdf-parse v2 (PDFParse class API)
  - Word (.docx) 提取：使用 mammoth.extractRawText()
  - TXT/Markdown：直接 UTF-8 解码
  - 支持中英文混合字数统计
  - 文件大小限制 200MB，类型校验（MIME 白名单）
  - 空文本 PDF（扫描件/图片）返回友好错误提示

- 新增上传接口：POST /knowledge/articles/upload
  - 使用 NestJS FileInterceptor 处理 multipart/form-data
  - 仅提取文本并返回，不直接创建文章（两步流程）
  - 返回：extractedText, suggestedTitle, wordCount, pageCount

- 新增 ExtractedTextResponse DTO
- KnowledgeModule 注册 TextExtractionService

## 前端 (admin-client)

- knowledge.api.ts：新增 uploadFile() 方法（FormData + 120s 超时）
- useKnowledge.ts：新增 useUploadKnowledgeFile hook
- KnowledgePage.tsx：
  - 新增 Segmented 切换器（手动输入 / 文件上传），仅新建时显示
  - 文件上传模式显示 Upload.Dragger 拖拽上传区域
  - 上传后自动提取文本，填入标题+内容字段
  - 提取完成自动切回手动模式，管理员可预览编辑后保存
  - 显示提取结果（字数、页数）

## 用户流程

新建文章 → 切换"文件上传" → 拖入/选择文件 → 系统提取文本
→ 自动填入标题+内容 → 管理员编辑确认 → 点击保存

## 依赖

- pdf-parse@^2.4.5（PDF 文本提取）
- mammoth@^1.8.0（Word 文档文本提取）
