Highlight Changes in Article Version History

Feature: Visual Diff for Article Version History

Problem
The current Article History only shows previous versions and allows restoring them, but it doesn't show what changed between versions. Users have to manually compare articles, which is inefficient for larger documentation.

Proposed Solution
Introduce a visual diff view in the version history that highlights:

• 🟢 Added content

• 🔴 Removed content

• 🟡 Modified content

Similar to GitHub, Google Docs Version History, or Notion, users should be able to quickly identify changes before restoring or reviewing a version.
