Delete a knowledge base article

Permanently deletes an article from your knowledge base.

⚠️ Warning: This operation cannot be undone. Make sure to backup any content
you want to preserve before deletion.

Note: This endpoint only deletes the specified article. If you have linked articles
in other locales (translations), they must be deleted separately. The system does
not automatically cascade deletions across linked articles to prevent accidental
loss of translated content.
