Implement ByStepFilter for AccompanyingPeriodStepHistoryFilters and its tests

A new feature has been added, the ByStepFilter, to the Chill project. The ByStepFilter provides a way to filter data in AccompanyingPeriodStepHistoryFilters based on certain steps. In addition, a new test suite has been introduced to ensure the correct functionality of this filter. The necessary translations for completing this feature have also been included.
