HTML Validation & Auto-Correction in OpenAI Translations

OpenAI translations now include HTML validation and correction.

If the source content contained invalid or broken HTML, those issues were previously carried over into the translated result. This happened because the translation prompt instructed the AI to keep the HTML markup unchanged.

Translations are now prompted to fix HTML markup when needed, while preserving the original structure and intent.

In addition, new technical safeguards detect HTML syntax issues that could otherwise break page layout or cause visible UI drift in translated content.
