As requested in https://openlmis.atlassian.net/browse/SELV3-61 new Approval screen need to be introduced for the SELV project. You can look into the mockup here.
In order to achieve the goal, we can create the UI for the new Batch Approval page just for the SELV project in selv-v3-ui repository. As for the backend part, there is a slight issue. Search endpoint for requisitions is returning them without the line items so we would need to retrieve them one by one which may be a performance issue for us,
In order to maximize the performance new endpoint would be needed in Requisition service.
