Update task completion to use local kanban state update

- Add updatedTask field to TaskCompletionResponse model from API
- Modify CompleteTaskView callback to pass back the updated task
- Add updateTaskInKanban() function to AllTasksView and ResidenceDetailView
- Move completed tasks to correct kanban column without additional API call
- Remove debug print statements from ResidenceDetailView
