Quarantine mode breakdown on the Quarantined Tests page

The analytics card on the Quarantined Tests page now splits the count into three widgets: total quarantined, Muted, and Skipped. Each widget has its own value, trend, and a chart that switches when you click it, so it is easier to see whether the suite is leaning on muted failures or actively excluding tests from execution. Selecting a widget pins the chart to that mode and persists the selection in the URL for sharing.
