[stable29] fix(settings): Hide forbidden UI elements for group managers

[susnux]

• Manual backport of [stable30] fix(settings): Hide forbidden UI elements for group managers #47651

Summary

1. The "recent" accounts API only works for admin and delegated admin -> hide for group managers
2. Group managers can not create new groups -> Hide the UI to add a new group for them
3. Accounts created by group managers require one of the groups, which is managed by the group manager, assigned. So if the group manager only manageres a single group, we should preselect that group.
