feat(push-task): connect notification module with task module

- Add task_type to w_push_events table and GORM models.
- Implement OnTaskCompleted callback hook in task executor to avoid circular dependencies.
- Implement task listener in push package to trigger notifications on task completion.
- Automatically resolve User objects from payload and results.
- Enhance UI to select task completed events and preview default templates.
- Update Swagger documentation.
