fix: SMTP SSL/TLS checkboxes not reflecting actual config in admin settings

The EmailStatusResponse didn't include smtp_use_tls/smtp_use_ssl fields,
and the JavaScript hardcoded defaults (TLS=true, SSL=false) instead of
reading from the API response. Now the API returns the effective values
and the UI displays them correctly.
