feat(Get-PreviewPanel): 🎨 add breakdown chart for Pester object results

* Implemented a breakdown chart displaying the counts of Passed, Failed, Inconclusive, and Skipped tests.
* Added a check to skip chart generation if the object is null or has all zero counts.
* Remove breakdown from title. It was too messy.
