Subject: [PATCH] =?UTF-8?q?=F0=9F=A9=B9(frontend)=20fix=20German=20languag?=
 =?UTF-8?q?e=20preference=20update?=
MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

German was missing from the frontend/backend language list in the
sync hook, causing user preference updates to be ignored.

Add the language to ensure preference changes are properly applied.
