Enhance Profile Endpoint Robustness and Security in profile.js

[smog-root]

Issue: #323

Kindly add all the labels! and assign me! @Harshdev098

Changes:

1. Error Handling in display Function:

• Added a check for empty results in the display function to avoid potential undefined errors when accessing result[0].
• If no data is found, the function now returns a 404 Not Found response.

2. Asynchronous Support in updateProfile:

• Wrapped db.query in a Promise to enable full asynchronous support with async/await, improving compatibility for future refactoring.

3. Token Security:

• Removed any logging of sensitive token information to align with security best practices, especially for production environments.

4. Optimized SQL Query Syntax:

• Switched from INNER JOIN to LEFT JOIN in the display function to ensure users without entries in the info_table are included if applicable.

5. Connection Management:

• Utilized a try...finally block to ensure connection.release() is always called in display, preventing potential connection leaks.

Testing:

• Tested for both existing and non-existing users to confirm proper responses (200 OK for valid users and 404 Not Found for invalid).
• Verified that sensitive token data is not logged.
• Confirmed that asynchronous calls work as expected with the new Promise wrapping in updateProfile.
