Is your feature request related to a problem? Please describe.

In #107505 we added metrics for when a lease is less preferred leases.preferences.less-preferred and satisfying no preference leases.preferences.violating. These are currently only viewable via custom metrics in DB Console.

Describe the solution you'd like

Add these metrics to the replication dashboard overlaid on the same chart.

Describe alternatives you've considered

Display these elsewhere as counters in overview page.
