Improve C360 Report pages to match the C360 Summary canvas style

The UX/UI on C360 Report pages ends up creating a lot of whitespace with overly large KPI widgets or other reports that get added.  This request is to add the same Canvas / Widget approach that is used on the C360 summary and bring that to the C360 Report pages to allow admins more flexibility in how they design the data/reports and provide a greatly improved experience to end users.
