Ubuntu 24.04 CIS 레벨 1 평가 이미지 구축

Create an Ubuntu 24.04 headless evaluation image with SSH, firewall,
audit logging, and the cis-benchmarks feature. Use key-only SSH,
disable root login, and add a locked-password operator account in sudo.
Add a scenario that waits for first-boot CIS remediation and runs the
Ubuntu 24.04 Level 1 server benchmark plus service and network smoke tests.
Do not call the result compliant; preserve failed controls and exceptions.
