Add end-to-end tests for parent item management

- Implement tests for creating, editing, and deleting chores, kindness acts, and penalties.
- Add tests to verify conversion of default items to user items and restoration of system defaults upon deletion.
- Ensure proper cancellation of creation and editing actions.
- Create a comprehensive plan document outlining the test scenarios and expected behaviors.
