Refactor Playwright tests and update configurations

- Consolidated kindness and penalty tests into single files to ensure serial execution and prevent conflicts.
- Updated Playwright configuration to define separate test buckets for child options and create child tests, ensuring proper execution order.
- Added new tests for child kebab menu options including editing, deleting points, and confirming child deletion.
- Removed obsolete tests for kindness and penalty default management.
- Updated authentication tokens in user.json for improved security.
- Enhanced test reliability by implementing retry logic for UI interactions in the create-child happy path test.
