feat: Optimize submission retrieval and processing flow

- Renamed variables from 'submission_record' to 'external_grader' throughout the codebase for better consistency with model naming
- Added new 'retry' status to integrate with submission processing retry services
- Removed unused 'is_processable' method that wasn't providing any value
- Enhanced test coverage
- Add new status external grader detail migration
