remote-support: Use remote server or realm UUID in support URL.

Because the remote support page now supports searching by UUID,
the support URL for remote billing entities, which is used for
sponsorship request emails and overdue invoice emails, can now
use the remote server or realm UUID.

Adds the remote realm UUID to the remote support view information.
