Fix Incorrect path for varbase-admin.admin-toolbar.theme.css causes warning after updating

Problem/Motivation

After updating Varbase to 10.0.4, a warning appears due to an incorrect file path in the varbase_admin module’s library definition. The admin-toolbar library points to theme/varbase-admin.admin-toolbar.theme.css, but the file is actually located in the css folder.

Steps to reproduce

Update Varbase to version 10.0.4.
Navigate to the admin interface or clear the cache.
Observe the following warning:

Warning: file_get_contents(modules/contrib/varbase_core/modules/varbase_admin/css/theme/varbase-admin.admin-toolbar.theme.css): 
Failed to open stream: No such file or directory in Drupal\system\Controller\CssAssetController->generateHash() 
(line 43 of core/lib/Drupal/Core/Asset/AssetGroupSetHashTrait.php).

Proposed resolution

• Option 1: Move the file to the theme folder to match the library definition.
• Option 2: Update the library path to point to the correct css folder
