feat(backup): enhance backup job with S3 upload handling and notifications

- Introduced a new notification class, BackupSuccessWithS3Warning, to alert users when local backups succeed but S3 uploads fail.
- Updated DatabaseBackupJob to track local backup success and handle S3 upload errors, improving error reporting and user notifications.
- Modified ScheduledDatabaseBackupExecution model to include a new s3_uploaded boolean field for tracking S3 upload status.
- Adjusted views and validation logic to reflect changes in backup execution status and S3 handling.
- Added tests to ensure the new s3_uploaded column is correctly implemented and validated.
