Add end-to-end tests for task assignment, modification, sorting, and child view updates

- Implement tests to verify that assigned titles display the correct child name in various chore and reward views.
- Create tests to ensure that child updates via SSE reflect correctly in the UI for task modifications, including point overrides and pending status resets.
- Add tests to validate the sorting order of tasks and rewards in both child and parent views, ensuring proper prioritization of pending, completed, and scheduled tasks.
- Introduce tests for scrolling behavior to ensure edited tasks are brought into view after modifications.
