Problem: Currently, GCP folder names (available as "Ancestor Display Name" in Dashboards) are missing as a dimension when defining Cost Categories.

Impact: Customers lwho have mature GCP folder structures but inconsistent project naming or tagging are unable to effectively group costs using their existing organizational hierarchy.

Requirement: Expose "Ancestor Display Name" or "Folder" as a selectable field in the rules engine for Cost Categories, similar to how it is currently available for Dashboards.
