This change updates internal data cleaning logic to use a shared maintenance approach for resetting stored values. It helps keep the codebase simpler and more consistent, with no expected change to day-to-day user workflows.

- Replaced custom model definitions in `task_gantt.test.js`, `task_gantt_dependency.test.js`, and `task_progress_gantt.test.js` with extensions of models from the project module.

- Moved shared model setup to project_test_models.js to avoid duplication and improve consistency.
