feat(ui): integrate KpiStatGrid for enhanced statistics display

Replaced existing KPI display implementations across multiple pages with the new KpiStatGrid component for a more consistent and visually appealing presentation of statistics. Updated the Backups, BGP, Certificates, Communities, Containers, Dashboard, and Data Collection pages to utilize the KpiStatGrid, improving the overall user experience and maintainability of the codebase. Additionally, added new dependencies in package.json for required libraries.
