Product Description Editor Now Disables WYSIWYG for Oversized HTML

Overview

Product description editing now includes a size-based quality safeguard in admin.

When a product description HTML field grows beyond 50,000 characters, the WYSIWYG editor is disabled for that field and the raw source is shown instead, together with a warning message. This helps admins identify corrupted or excessively large description content and edit it directly without loading the full rich-text editor.

The goal is to keep description quality under control and reduce cases where oversized HTML slows down admin editing or storefront performance.
