Pull Request Overview

This PR fixes email visibility for team admins and owners when querying user profiles via the POST /list-users endpoint. Previously, when email visibility was configured as "visible_to_self", even team admins couldn't see team members' emails. Now, admins and owners can see team member emails regardless of the configured email visibility setting.

Key Changes

• Modified email visibility logic to always grant email access to team admins and owners
• Added integration test to verify the fix
• Added API helper function for testing the /list-users endpoint

at this point, the following brig integration tests fail:

'/basic \/calls\/config - 200/'
'/multiple servers using files \/calls\/config - 200/'
'/multiple servers using SRV \/calls\/config - 200/'
'/\/users\/.(Creator,EmailVisibleToSelf)/'
'/\/users\/.(Member,EmailVisibleToSelf)/'
'/\/users\/:uid.(Creator,EmailVisibleToSelf)/'
'/\/users\/:uid.(Member,EmailVisibleToSelf)/'

some of the failures look unrelated, but not flaky. strange.
