- Updated the PermissionCatalog to remove unnecessary permissions for assignment submissions.
- Modified RolePermissionSeeder to align with the updated permissions.
- Enhanced useServerTable hook to support resetKeys for Inertia's reset visit option.
- Removed obsolete columns.tsx file related to assignment columns.
- Revamped assignment index page to utilize InfiniteScroll and improved UI components.
- Introduced new assignment status management with enums and updated database schema.
- Created GradeSubmissionRequest for validation of submission grading.
- Implemented score editing functionality in submission index with real-time updates.
- Added accordion component for better UI organization in assignment descriptions.
