Move adminInterface check to shouldShowGlobalSiteSidebar

[okmttdhr]

Related to https://github.com/Automattic/dotcom-forge/issues/5609

Proposed Changes

This pull request refactors the location of the adminInterface check, moving it into the shouldShowGlobalSiteSidebar function.
This change aims to streamline code by reducing the number of code seams. Previously implemented as a hook, the adminInterface check has been transformed into a selector, so it can now be utilized within both functional and connected components.

Testing Instructions

• Open Calypso Live
• Go to /sites, /read, /me and verify it shows Global View sidebar
• Prepare a site with the classic view, and then go to a Calypso page (e.g., /home/your-site), verify it shows Global Site View sidebar
