Fix automatic database backup system for production

Resolves an issue where the automatic backup service was not initialized in the production environment, preventing daily backups. Updates `docker-compose.yml` to include a backup directory and volume, modifies `index.production.ts` to import and initialize the backup service, and enhances `replit.md` with details of the fix. A new verification script `scripts/verify-backup-system.sh` is added to confirm the system's functionality.
