- Added BullMQ queue (`backup.queue.ts`) for scheduling backups. - Created worker (`backup.worker.ts`) to handle pg_dump, gzip compression, S3 uploads, and retention cleanup. - Implemented restore logic (`backup.restore.ts`) to handle recovery from S3 or local storage. - Updated `env.config.ts` with backup configuration and secret masking. - Added 11 new environment variables to `.env.example` for S3, cron, and retention settings. - Integrated worker startup and graceful shutdown into `index.ts`. - Added AWS SDK dependencies (`@aws-sdk/client-s3`, `@aws-sdk/lib-storage`) to `package.json`. Closes StellarDevHub#738
