When `authenticate_user` is called with a username that doesn't exist in the database, we still run `verify_password` against a dummy hash.

This ensures the endpoint takes roughly the same amount of time to respond whether the username is valid or not, preventing **timing attacks** that could be used to enumerate existing usernames.
