Subject: [PATCH] Fix buggy code input field in admin.php

- Included codemirror/addon/mode/loadmode.js script.
- Configured CodeMirror.modeURL.
- Updated change_editor function to correctly map dropdown selections to CodeMirror mode names and load them dynamically.
- Handled missing modes gracefully.
