Research if we can fully remove GTM from dashboard

We would still like to monitor folks hitting certain milestones (creating entity, entering certain info, etc.) to help with support.

Since many of the Google endpoints serve up jsonp they cause issues with CSP validators.

We could look into making these calls from an edge function or cloud run or something and make the analytic calls from there.

Marking as ongoing as I want to complete within 3 months and will start putting in an hour or two a week into this effort.
