The cohort reporting view can now be connected to related list and form screens without adding those screens directly to the main action. This gives teams more control over navigation while keeping menus and actions simpler for users.

In some cases we want to link the cohort view with a list view and a
form view, but we don't want to add them to the action.

This fixes the spacing around the database list in the database manager after the Bootstrap upgrade changed the previous layout behavior. The page should now look cleaner and more consistent for users managing databases.

Before BS4 we had use class 'list-group' for listing Databses,
which was adding 20px padding-bottom, but that not case after upgrading BS4,
so for fixing layout added 'mt-3' BS4 class.
