✨ feat: Implement new models and migration logic

- Implemented various model classes in /models, including User, Class, ClassUser, GroupBoard, GroupCode, GroupSchedule, Role, and Attendance.
- Each model class is designed with appropriate GORM tags for effective database mapping.
- Updated the migration logic in /migration/migration.go to include these new models.
- Modified main.go to facilitate optional migration execution based on the RUN_MIGRATIONS environment variable.
- Removed unnecessary logic for migration.
