Documentation and Template Updates

• Added a comprehensive pull request template in .github/PULL_REQUEST_TEMPLATE.md to guide contributors and ensure consistent PR submissions.

Repository Branding and Links

Authentication Documentation

• Added new guides for setting up authentication in Azure App Service and creating new App Registrations, complete with step-by-step instructions and screenshots in content-gen/docs/AppAuthentication.md and content-gen/docs/create_new_app_registration.md. [1] [2]

Frontend User Info Extraction

• Refactored the user info fetching logic in content-gen/src/app/frontend/src/App.tsx to use Azure App Service's built-in /.auth/me endpoint, extracting user ID and display name from claims for improved reliability and clarity. [1] [2]

CI Improvements
