Fix: Enable Universal Vercel Deployment + Enhanced URL Visibility for All Contributors

🎯 Problem Solved

Contributors like @violaberg were unable to deploy their PRs to Vercel, encountering this error:

Error: No existing credentials found. Please run `vercel login` or pass "--token"

Additionally, when deployments succeeded, the frontend URLs were buried in logs and difficult to find, making it hard for reviewers and contributors to quickly access and test the deployed changes.

🚀 Solution Overview

This PR implements a two-part solution:

1. 🔐 Universal Deployment Access - Enable any contributor to deploy without individual Vercel accounts
2. 📍 Enhanced URL Visibility - Make deployment URLs prominently visible across multiple interfaces

🛠️ Technical Changes

1. Fixed Authentication Issues

Before:

vercel pull --yes --environment=preview --token=${{ secrets.VERCEL_TOKEN }}

❌ Failed for contributors without pre-linked projects

After:

# Ensure .vercel directory exists and create project.json
mkdir -p .vercel
echo "{\"orgId\":\"$VERCEL_ORG_ID\",\"projectId\":\"$VERCEL_PROJECT_ID\"}" > .vercel/project.json

# Try vercel pull first, if it fails, proceed with direct deployment
if vercel pull --yes --environment=preview --token=${{ secrets.VERCEL_TOKEN }}; then
  echo "✅ Successfully pulled Vercel configuration"
  vercel build --token=${{ secrets.VERCEL_TOKEN }}
  DEPLOYMENT_URL=$(vercel deploy --prebuilt --token=${{ secrets.VERCEL_TOKEN }})
else
  echo "⚠️ Vercel pull failed, proceeding with direct deployment"
  DEPLOYMENT_URL=$(vercel deploy --token=${{ secrets.VERCEL_TOKEN }})
fi

✅ Works for all contributors with fallback strategy

2. Enhanced URL Visibility

A. Improved Console Output

🎯 BACKEND DEPLOYED SUCCESSFULLY!
📍 Backend URL: https://backend-xyz.vercel.app

🌟 FRONTEND DEPLOYED SUCCESSFULLY!

B. GitHub Actions Summary

• Appears prominently in Actions interface
• Quick test links for immediate verification

C. Smart PR Comments
