i18n(permission-overrides): wrap DENY option + explicit CreateAction labels

- 'DENY — interzice dreptul' select option was missing __() wrap
- CreateAction/EditAction now have explicit label/modalHeading so
  the modal shows 'Добавить исключение прав' instead of
  'Создать User Permission Override' (auto-generated from class name)
