Can't translate content anymore

Problem/Motivation

When the module is installed and countries with languages are added, the front-end functionality works correctly. However, if I attempt to translate a node, clicking "Edit" redirects me to the source language version of the node instead of staying in the desired translation context. This seems to occur because there is no language prefix applied on admin pages.

Steps to reproduce

• Install the Language Country Negotiation module.
• Add countries and assign languages.
• Set up a translatable content type.
• Attempt to edit a node in a language other than the source language.

Expected Behavior

The edit page should respect the current language context when translating nodes and allow editing in the selected language.

Actual Behavior

The edit page defaults to the source language version of the node, ignoring the language context.

Possible cause

This issue likely occurs because there is no language prefix applied to admin pages, which causes the language negotiation to default to the source language.
