feat(config): add configurable check-in date restriction and persistent logging

- Add ENABLE_CHECKIN_DATE_RESTRICTION environment variable to allow flexible check-in testing
- Replace NODE_ENV check with configurable flag in check-in validation logic
- Implement persistent logging with external Docker volumes (slc_logs_prod)
- Configure backend-prod and nginx-prod to write logs to /var/log/app/ and /var/log/nginx-app/
- Increase log rotation limits (50MB, 10 files) for better debugging
- Update .env.example files with new check-in configuration
