1. 合并 files-page 与 pdf-admin 为统一文件管理页 /api/files-page:
- 新增 GET /api/admin/files/with-pdf 接口，以 uploaded_files 为基础，
用 pdf_jobs.source_file_id / output_file_id 内存匹配，为关联文件标注
转换状态、用户软删标记与角色(源epub/产物PDF)
- PdfJobOut 补 source_file_id / output_file_id 字段
- file_browser 新增 PDF 任务列(状态徽标/软删标记/硬删任务按钮)
- 删除 /api/pdf-admin 路由及 static/pdf_admin.* 三个文件
2. 新增导航页 /api/index，卡片式收集所有页面入口；
各子页(upload/whiteboard/system_status/files-page)脚注加返回导航链接
3. 更新 docs/routes.md、docs/configuration.md 同步说明
测试: pytest tests/test_pdf_service.py 7 passed; 手动校验各页面路由与合并接口响应
