Drop `ChartView._maxmin()` usage in `.ui._fsp` 

Removes the multi-maxmin usage as well as ensures appropriate `Viz` refs
are passed into the view methods now requiring it. Also drops the "back
linking" of the vlm chart view to the source OHLC chart since we're
going to add this as a default to the charting API.
