Pull Request Overview

Implements correct active/passive status determination for active-active domains in the Domain Metadata section by introducing a new helper function that checks activeClustersByRegion instead of relying solely on activeClusterName.

• Created isActiveCluster helper to handle both active-active and active-passive domain logic
• Updated cluster metadata component to use the new helper for accurate status labeling
• Added comprehensive test coverage for the new functionality
