fix: code scanning alert no. 167: Log Injection

[yacosta738]

Fixes https://github.com/dallay/lyra/security/code-scanning/167

To fix the log injection issue, we need to sanitize the query.username before logging it. The best way to do this is to remove any potentially harmful characters, such as newlines, that could be used to forge log entries. We can use the replace method to replace newline characters with an empty string. This change should be made in the handle method of the AuthenticateUserQueryHandler class.
