LPS-38253 Usability improvement, show header with back when creating or editing a team
LPS-38253 Usability improvements: remove the link "View Members" from the toolbar since it no longer makes sense to have it by itself. Instead, ensure that all UIs have a header with a back link. In some cases, to simplify, I've removed a previously existing header that was only shown when outside of the Control Panel with the new header that should be shown always.
