Add Send-Only Email Template for Domain Connect

[xwiz]

Description

Added a new Domain Connect template venmail_email_send_only for send-only email hosting mode. This template excludes MX records and website redirection CNAME records, which are not needed for send-only email functionality. The template includes only the essential DNS records required for email sending: DKIM, SPF, and DMARC.

This addresses the issue where send-only mode was generating placeholder MX records like %mx_points% 10 and %mx2_points% 20 because the original template always included MX records regardless of the service mode.
