Tasks split out from umbrella ticket T260816: VE Dialog on the Test Instance: Sidebar and Dialog layout/behaviour changes
Behavior for adding/removing parameters is done in T261504.
For the sidebar:
- Group parameters by required, suggested, and optional in the side bar, adding subtitles for each section.
- If a section has no parameters, then do not show the title/section.
- ParamOrder works like in TemplateWizard: order by priority group first, then sort by ParamOrder within each group.
