🛡️ Sentinel: [MEDIUM] Fix SSRF in sandboxed_web_e2e.py readiness probe

[seonghobae]

🎯 What: scripts/ci/sandboxed_web_e2e.py의 wait_for_url 함수에서 SSRF 방지를 위해 호스트네임을 로컬호스트로 제한하는 검증 로직을 추가하고, 이를 검증하는 테스트 코드를 작성했습니다.

⚠️ Risk: 검증되지 않은 URL 호스트네임이 외부 IP 주소나 민감한 내부 네트워크(예: 169.254.169.254)를 가리킬 경우, CI 환경에서 Server-Side Request Forgery (SSRF)를 통해 내부 리소스가 유출되거나 원치 않는 네트워크 스캔이 발생할 위험이 있습니다.

🛡️ Solution: urllib.parse.urlparse를 사용하여 URL을 파싱하고, hostname이 명시적으로 localhost, 127.0.0.1, ::1 중 하나인지 검사합니다. 조건에 맞지 않으면 외부 호스트네임 호출을 차단하기 위해 ValueError를 발생시킵니다. 또한 해당 검증 로직이 의도대로 동작하는지 보장하기 위해 tests/test_sandboxed_web_e2e.py에 단위 테스트를 추가하여 테스트 커버리지를 100%로 맞추었습니다.

Closing as superseded by #1314 exact head 3525287. The proposed hostname tuple is incomplete for userinfo-confused URLs, mapped IPv6 semantics, and poisoned/mixed localhost resolution. #1314 implements and tests those fail-closed cases on current main with full 100% coverage. Branch history remains recoverable.

Understood. Acknowledging that this work is now obsolete as it has been superseded by #1314, and stopping work on this task.
