fix(dashboards): control legends individually

[nikkikapadia]

Previously charts that have the same series on their legend were controlled together (toggling one off would toggle them both off). Now the legend can be controlled individually as they are associated with the widget id. Since it is stored in the query (in the format widgetId-seriesName1-seriesName2-...), this also fixes the issue where selecting a new time range or other filter changes reset what series were selected.
