feat: add scheduled quiz notification task and enhance Quiz schema with scheduleId

- Introduced a new cron job in CronService to check for schedules with status WAITING_QUIZ and notify customers to complete their quizzes.
- Enhanced the Quiz schema by adding an optional 'scheduleId' argument to facilitate quiz retrieval based on specific schedules, improving user experience and data association.
- Updated role-based access control logic to ensure proper handling of quiz queries for customers and center mentors.
