Subject: [PATCH] fix partial field translation overwriting entire translation

When re-translating only changed fields (e.g., just ingredients), the partial
result was replacing the entire English translation, causing name, short_name,
description, and category to be lost.

Now merge partial translations with existing translation data to preserve
unchanged fields while updating only the modified ones.
