Weston Ruter 8fed77574c Customize: Return user to referring URL when leaving Customizer in absence of return query param.
When referring URL is not available, default returning user to frontend URL instead of admin URL. Themes page is updated to include the `return` path in Customizer links.

Props McGuive7, westonruter.
Fixes #32637.
