AWS comprehend-medical documentation change
Summary
Renamed file from security-compliance.md to compliance-validation.md, updated PDF reference, and changed 'Logging Amazon Comprehend Medical API calls by using AWS CloudTrail' to 'CloudTrail logs'
Security assessment
This is a documentation restructuring that renames security-related files and updates terminology. The change maintains security compliance documentation but doesn't add new security features or address specific vulnerabilities. The terminology change from 'Comprehend Medical' to 'Amazon Comprehend Medical' is consistent branding.
