Graceful Handling of Removed Users

When a user is removed from a Lytics account, it's typical for the tasks or audiences they created to remain active. Previously, this situation led to errors across the interface, particularly when reviewing a Source or Destination in Conductor. A warning would appear with minimal details following the user's removal. This behavior has now been amended, and the interface will display "Removed User" in the "created by" field to clarify the status.
