Change "is admin" and "is active" values to checkboxes on the settings page

[Vylpes]

AS an admin I should see checkboxes for a user's "is admin" and "is active" toggles SO THAT I can change these in a manor that makes more sense

Acceptance Criteria

AS an admin GIVEN I am on the users edit page WHEN I want to change the "is admin" value THEN I should see this as a checkbox

AS an admin GIVEN I am on the users edit page WHEN I want to change the "is active" value THEN I should see this as a checkbox

Notes

• Currently it is displayed as a dropdown, as this is only 2 options (yes/no) then it should be a checkbox
