fix: update default smtp username

- Change default SMTP username in ApplicationMailer to
  'noreply@mail.frytea.com'
- Comment out previous username in credentials to
  avoid confusion
- Ensure updated username is reflected in production
  environment settings

This update improves email configuration organization, making it
clearer and reducing the risk of misconfiguration, as the hardcoded
value in the mailer takes precedence.
