Ensure Correct Theme Is Loaded When Using the Dashboard Module

Problem/Motivation

When using the Dashboard module with Layout Builder, the theme negotiator does not account for dashboard-specific routes. As a result, the wrong theme (typically the front-end theme) is loaded when accessing Dashboard layout pages. This causes inconsistencies in styling, layout issues, or even administrative UI problems.

Steps to reproduce

1. Enable the Dashboard module.
2. Access the dashboard layout builder page.
3. Notice that the incorrect theme is used instead of the admin theme, breaking visual consistency and sometimes functionality.

Proposed resolution

Update the VarbaseLayoutBuilderThemeNegotiator logic to include dashboard layout routes as valid candidates for theme negotiation.
