Add help text and user login block to Backdrop demo front page
The front page of the Backdrop Civi demo at https://bmaster.demo.civicrm.org/ displays the generic Backdrop "Your first post!"
It should instead display the same (or nearly the same) text as is displayed on https://dmaster.demo.civicrm.org/, and should ideally also have a user login block in the sidebar.https://dmaster.demo.civicrm.org/
How can these changes be made in a way that endures through the periodic demo database resets? Happy to help do the work but I don't know how to make those changes stick.
