WIP: Add details for g_compliance_dashboard_feature flag

What does this MR do?

The g_compliance_dashboard_feature feature flag did not yet have URL and group details, so this adds them.

Note: At first it looked like this feature flag had been removed, but there is a test that indicates it is still in use, so it may actually be a dynamic feature flag that is based on the Redis counter name.

Does this MR meet the acceptance criteria?
