Subject: Add custom SMTP authentication support

- Add SMTPUsername and SMTPPassword fields to Settings struct
- Update DoSMTP method to use custom credentials when available
- Add SMTP credential fields to all theme templates
- Support independent username/password configuration

Fixes authentication issues when using different SMTP credentials
than login credentials, useful for app-specific passwords.
