Add build step for Astrolabe app in CI workflow to compile frontend
assets before docker-compose starts.
Changes:
- Install Node.js 20 for Astrolabe build
- Run composer install --no-dev for Astrolabe PHP dependencies
- Run npm ci and npm run build to compile frontend assets
This ensures the Astrolabe app is properly built in CI, similar to
the existing OIDC app build process.
