Only set the specific view's yrange per quote
Somewhat of a facepalm but, for incremental update of the auto-yrange from quotes in the display loop obviously we only want to update the associated `Viz`/viewbox for *that* fqsn. Further we don't need to worry about the whole "tick margin" stuff since `._set_yrange()` already adds margin to the yrange by default; thus we remove all of that.log_linearized_curve_overlays
