missing HTTP response validation in the profile fetch logic

Related Issue

• Closes: 🐛 Bug Report: Missing HTTP Response Status Check #639

---

Description

This PR resolves a critical bug where the application would silently fail or crash if the GitHub API returned a non-200 response (such as a 404 for a missing user). Added an if (!userRes.ok) check to validate the HTTP response status before attempting to parse the JSON.

---

How Has This Been Tested?

• Ran the local development server.
• Searched for a valid GitHub username to ensure the profile loads correctly.
• Searched for an invalid GitHub username to verify the app throws the error gracefully instead of crashing the UI.
