When we cleanup event history (both Camunda and external), we don't correct the existing traces and sequences that we have stored. This results in incorrect event counts in the events table, and also possibly impacts suggestions and autogeneration. We should explore ways in which we can correct the traces and sequences on history cleanup so they accurately reflect.

ATs:

• Event traces don't contain references to events that have been historically cleaned up
• Event counts are accurate even if history cleanup has removed events
