Security fix: Disable the X-Powered-By header in Express to prevent
disclosure of server technology information. This header can reveal
that the application is using Express.js, which could help attackers
identify potential vulnerabilities.
The fix adds app.disable('x-powered-by') after creating the Express app
to prevent the server from sending this header in responses.
