#196617)

## Summary

This PR made some updates to the insights KPI following
#195509

- Updated all the counts to be total
alerts/misconfigurations/vulnerabilities
- Clicking on the count badge opens timeline (alerts) or entity preview
- Revert the order of the distribution bar for alerts to align with
others
