Generate application assessment report and architecture diagram

[Copilot]

Analyzed PhotoAlbum-Java application for Azure migration readiness and documented its architecture using AppCAT assessment tools.

Assessment Report

Location: .github/modernize/report.json

AppCAT analysis evaluating the application against three Azure compute targets:

• Azure Kubernetes Service (AKS)
• Azure App Service
• Azure Container Apps

Identifies migration blockers, code patterns requiring changes, and provides Azure-specific recommendations.

Architecture Diagram

Location: .github/modernize/assessment-diagram.md

Mermaid diagram documenting:

• Layered architecture (MVC pattern with service layer)
• Component relationships (Controllers → Services → Repository → Oracle DB)
• Technology stack (Spring Boot 2.7.18, Java 8, Thymeleaf, Oracle JDBC)
• Data flow patterns for photo upload, gallery view, and detail view
• Migration considerations for Azure deployment

Both artifacts serve as foundation for planning modernization efforts and Azure migration strategy.
