Apply Composer changes: comprehensive API updates, migrations, middleware, and infrastructure improvements

- Add comprehensive database migrations (001-024) for schema evolution - Enhance API schema with expanded type definitions and resolvers - Add new middleware: audit logging, rate limiting, MFA enforcement, security, tenant auth - Implement new services: AI optimization, billing, blockchain, compliance, marketplace - Add adapter layer for cloud integrations (Cloudflare, Kubernetes, Proxmox, storage) - Update Crossplane provider with enhanced VM management capabilities - Add comprehensive test suite for API endpoints and services - Update frontend components with improved GraphQL subscriptions and real-time updates - Enhance security configurations and headers (CSP, CORS, etc.) - Update documentation and configuration files - Add new CI/CD workflows and validation scripts - Implement design system improvements and UI enhancements

+/**
+ * Comprehensive Audit Logging Service
+ * 
+ * Implements audit logging per DoD/MilSpec requirements:
+ * - NIST SP 800-53: AU-2 through AU-12 (Audit and Accountability)
+ * - NIST SP 800-171: 3.3.1-3.3.8 (Audit and Accountability)
+ * - DISA STIG: Application Security, Database Security
+ * 
+ * Features:
+ * - All security-relevant events logged
+ * - Tamper-proof audit logs (cryptographic signatures)
+ * - Immutable audit trail
+ * - Real-time log monitoring
+ * - 7+ year retention for classified data
+ * - Log integrity verification
+ * - Centralized log aggregation
+ * - SIEM integration
