Feature/filter accounts by role

[tobias-wiese]

Description

Implements issue #262

Reason for this PR

• The admin did not have any possibility to filter the accounts, he gets from the backend

Changes in this PR

• I added a simple filter bar consisting of buttons, that allow to filter the shown accounts. To do so, the object containing all users (gotten from the API call in the account list) is just filtered, s.t. no additional API calls like getAdmins are needed. The filter is set outside the suspense wrapper of the account list itself, s.t. refreshing the account list does not reset the selected filter.

Type of change (remove all that don't apply)
