- Calculate overcommit percentages and resource quota coverage
- Update frontend to use new overcommit data structure
- Fix issue where Cluster Overcommit Summary was showing all zeros
- Use regex pattern pod=~"{workload}.*" in workload metrics API
- This matches the fix applied to historical analysis
- Should resolve issue where resource-governance workload data was not being retrieved
- Both historical analysis and workload metrics now use consistent pod name matching
- Unify Prometheus queries between namespace analysis and historical analysis
- Fix efficiency calculations to prevent division by zero
- Remove duplicate validations in validation service
- Improve frontend data display with clear numerical values
