Emailed chat transcript should use full domain name, or be admin-settable
Emailed transcript has subject "Chat transcript on <example.com>..." and email body starts, 'Chat on <example.com>".
Problem where we use tawk, multi-tenant systems, where different subdomains distinguish different clients (abc.example.com, xyz.example.com, etc.) We use different site-id for each, so tawk can distinguish.
Either, have transcript use full domain ("Chat on abc.example.com"), or provide a site-level configuration "display name", and use "Chat on ABC Corp."
