fix : remove console.log exposing Firebase API key in browser console

[tmdeveloper007]

Summary of What Needs to be Done

Remove the console.log statement in frontend/src/utils/firebase.js that logs the Firebase API key to the browser console. Exposing API keys in client-side console output is a security concern as it can be read by anyone inspecting browser DevTools.

Changes that Need to be Made

• Delete line 4 in frontend/src/utils/firebase.js:
  console.log("Firebase API Key:", import.meta.env.VITE_FIREBASE_API_KEY);

Impact that it would Provide

• Eliminates a potential security risk where the Firebase API key could be exposed to unauthorized users via browser DevTools
• Keeps production environment variables out of developer console output
• Aligns with best practices for handling sensitive configuration in client-side code
