Fix deploy-user-app workflow heredoc parsing in Dockerfile generation step

[Copilot]

The Build and Deploy Parshant1231/dev_deploy job was failing before image build due to a shell parse error in the Select or generate Dockerfile step (syntax error: unexpected end of file). The failure came from an incorrectly terminated heredoc in .github/workflows/deploy-user-app.yml.

• Root cause

  • The generated Dockerfile heredoc terminator (EOF) and body were indented inside the run block, which caused Bash to miss the heredoc close token and abort the step.

• Change made

  • Updated the heredoc block in deploy-user-app.yml so heredoc content and closing EOF are emitted in a shell-safe format.
  • No workflow logic changes beyond fixing heredoc parsing.

• Relevant patch

  cat > generated.Dockerfile << 'EOF'
  FROM node:18-alpine
  WORKDIR /app
  COPY package*.json ./
  RUN npm ci --only=production
  COPY . .
  EXPOSE 3000
  CMD ["node", "index.js"]
  EOF
