Summary Multi Plot : Improve default behaviour (#8885)

* Summary Multi Plot : Improve default behaviour

- Perform zoom when stepping to next item
- Set defaults for range aggregation and source stepping dimension based on content when creating a multi summary plot

* Plot Axis Appearance : Do not use bold for text configuration

* Improve how scale factor for legend values are computed

* Improve defaults for range aggregation and step dimension

* Reorder Capability : Get UI item before reordering is issued

Get UI item before reordering is issued, as this operation will invalidate the tree model
