Fix #47: Complete fix for Save Settings not working

Root Cause: The saveSettings() function was trying to get email from formData.get('email'), but no field with name="email" existed in the form. Additionally, the Private CA configuration panel wasn't being shown correctly due to ID mapping mismatch (private_ca → private_ca-config instead of private-ca-config).

Solution:

1. Modified saveSettings() to extract email from the selected CA provider's configuration section (Let's Encrypt, DigiCert, or Private CA)
2. Added explicit caProviderToConfigId mapping to correctly handle the private_ca → private-ca-config ID translation
3. Improved error messages to indicate which CA provider section requires the email address

Changes:

• templates/settings.html: Updated email collection logic and CA provider config ID mapping

Testing:

• Verified settings save correctly for all CA providers (Let's Encrypt, DigiCert, Private CA)
• Confirmed no more "An invalid form control is not focusable" browser console errors
• Validated proper show/hide of CA configuration sections

Closes #47
