Fix: Implement DOMPurify to sanitize HTML content before rendering (#1498)

### What problem does this PR solve?

Scripting (XSS). The issue was caused by the unsafe usage of
`dangerouslySetInnerHTML` without proper sanitization of user input.

### Changes

- Updated the following components to use DOMPurify:
-
`web/src/pages/add-knowledge/components/knowledge-chunk/components/chunk-card/index.tsx`
  - `web/src/pages/chat/markdown-content/index.tsx`
-
`web/src/pages/add-knowledge/components/knowledge-setting/category-panel.tsx`
