Switch to sameersbn/squid image and simplify verification

- Replace ubuntu/squid with sameersbn/squid:latest (more reliable)
- Remove shared volume mounts that may cause permission issues
- Simplify verification steps since we can't access service container logs
- The test validates proxy works by verifying cache operations succeed
  when direct access is blocked by iptables
