chore: bump version to 1.0.20

- Add detailed validation for SMTP configuration
- Add specific error messages for common SMTP issues (connection, auth, network)
- Add logging to help debug email configuration issues
- Check for masked passwords that shouldn't be used for sending
- Parse smtp_port as integer and handle boolean smtp_secure properly

This helps identify the exact cause of email sending failures instead of
generic 500 errors.
