Hard-coded API Keys in Source Code (Security Vulnerability) GSSOC-25

[piyushkumar0707]

The application has hard-coded API keys exposed in the source code, specifically in utils/chatbot.py lines 6-7.
Why This Issue Matters:

1. Security Risk: API keys are publicly visible in the repository
2. API Abuse: Anyone can use these keys, potentially exhausting quotas
3. Best Practices: Violates standard security practices for credential management
4. Production Ready: The app can't be safely deployed with hard-coded keys
