As a cost manager, I want to integrate Azure billing data with my OpenShift cost data

Description: As a cost management administrator running OpenShift on Azure, I want to configure Azure cost integration so that I can view consolidated reports showing both my OpenShift workload costs and the underlying Azure VM, storage, networking, and other service costs.

Definition of Done:

• [ ] Azure billing data is successfully ingested
• [ ] OpenShift nodes are mapped to their underlying Azure VMs
• [ ] Consolidated cost reports show both OpenShift and Azure costs
• [ ] Cost allocation works correctly across subscriptions and OpenShift namespaces
• [ ] Integration tests validate data accuracy
