Assess application for Azure cloud migration readiness

[Copilot]

Runs AppCAT static analysis on the Photo Album Java application to identify migration issues and blockers across Azure compute targets.

Changes

• Assessment report — AppCAT analysis executed against azure-aks, azure-appservice, and azure-container-apps targets in issue-only mode; versioned report saved to .github/modernize/assessment/reports/report-20260520034607/report.json
• AppCAT config — Assessment configuration at .github/modernize/appcat/assessment-config.yaml defining target environments and analysis mode
• Cleanup — Removed ccacontext scaffolding and skill files used to bootstrap the assessment workflow

Original prompt

Task: Assess the application

Run core assessment

Use the 'assessment' skill to analyze the application and generate the assessment report.
This skill runs AppCAT (Azure Migrate application and code assessment) to detect migration issues.

Commit and PR instructions

Before committing, use 'git add -f .github/modernize/assessment' to force-add the assessment outputs under that directory so they are included in the pull request even if a .gitignore file would otherwise exclude them.. Only the files that were actually generated will be staged.

When creating the PR, propose a proper title, but DO NOT contain any tool/tech stack on it, e.g. 'Assessing project with AppCAT' is not good as AppCAT is one of the assessing tool.
