Feature: #108694 - Context menu items to edit site configuration for pages 

Description 

Two new context menu items have been added for pages that are site roots:

• Edit Site: Opens the site configuration editor for the site associated with the page.
• Edit Site Settings: Opens the site settings editor for the site.

These items appear directly after the "Edit" item in the context menu and are only visible to admin users on pages that have a site configuration.

Impact 

Admin users can now quickly access the site configuration and site settings directly from the context menu when right-clicking on a site root page. This improves the workflow for managing sites without needing to navigate to the Site Management module first.
