Closes #495 — Refactor CORS Configuration into a Dedicated Configuration Module

✅ Changes Made

• Extracted the allowedOrigins logic and cors() configuration callback from app.js.
• Created a new ES Module file config/cors.js to centralize all CORS settings.
• Exported the configured corsMiddleware using ES Module export default syntax.
• Imported and applied the new middleware in app.js.

🧪 Testing Checklist

• Server starts successfully.
• API calls from localhost (development) still work perfectly.
• API calls from the production FRONTEND_URL still work perfectly.
• The app's CORS behavior remains completely unchanged.

📌 Benefits Achieved

• ✅ Cleaner app.js entry point.
• ✅ Better Separation of Concerns.
• ✅ Easier maintenance (add/remove origins in a single file).
