AWS vpc documentation change
Summary
Updated terminology from 'EIP' to 'Elastic IP address' throughout documentation for consistency and clarity. Removed redundant acronym usage in section headers and clarified quota/configuration requirements.
Security assessment
Changes are purely terminological clarifications and documentation formatting improvements. No security vulnerabilities, mitigations, or security features are mentioned. The network border group matching requirement is a configuration prerequisite rather than a security control.
