🔐 refactor: MCP User Variable Description Rendering (#10769)

* refactor: Add back user variable descriptions for MCP under input and not as Tooltips

- Integrated DOMPurify to sanitize HTML content in user variable descriptions, ensuring safe rendering of links and formatting.
- Updated the AuthField component to display sanitized descriptions, enhancing security and user experience.
- Removed TooltipAnchor in favor of direct label rendering for improved clarity.

* 📦 chore: Update `dompurify` to v3.3.0 in package dependencies

- Added `dompurify` version 3.3.0 to `package.json` and `package-lock.json` for improved HTML sanitization.
- Updated existing references to `dompurify` to ensure consistency across the project.

* refactor: Update tooltip styles for sanitized description in AuthField component
