[CC-004] Region filtering inconsistent across cloud cost collectors

[LFigg]

Description

Region filtering behavior is inconsistent across cloud providers. Some collectors filter by region, others don't.

Location

• File: cost_collect.py - Various cost collection functions

Impact

• Inconsistent behavior depending on cloud
• Potential for missing or duplicate cost data

Suggested Fix

Standardize region handling:

• AWS: Region-specific costs available via Cost Explorer grouping
• Azure: Location-based filtering supported
• GCP: Region available in BigQuery billing data

Document expected behavior and ensure consistency.

Priority

Low
