Fix child item icon alignment in Views and AI Generated sections by

increasing left margin from 4 to 18px so icons align under the parent

section header icons (past the chevron). Replace StackPanel layout with

Grid + GridSplitters for independently resizable Datasets, Views, and

AI Generated sections. Each section scrolls within its own allocated

height. Section heights persist via IPluginSettings (DatasetsSectionHeight,

ViewsSectionHeight, AiGeneratedSectionHeight). Set IsContentScrollable

to false on PluginSidebar since sections manage their own scrolling.

Increase ListBox.sidebarList horizontal margin from 4 to 8 so

selection/hover rectangles don't stretch edge-to-edge. Remove the

New Dataset button from the sidebar header per user request.

Replace manual Border + DockPanel + resize handle with the shared

PluginSidebar from UI.Adaptive (same control Notes uses). This ensures

the sidebar background, resize handle, and overall structure match

Notes exactly — using ThemeBackgroundBrush instead of the previous

ThemeSurfaceRecessedBrush which caused a visible mismatch. Removes

manual resize pointer handlers from code-behind in favor of

PluginSidebar.WidthChanged event. Grid columns simplified from

Auto,Auto,* to Auto,*.

Strip default ListBoxItem backgrounds via sidebarList class styles:

transparent at rest, ThemeSurfaceElevatedBrush on hover, CornerRadius 6,

bold title on selected. Removes card-like appearance to match Notes'

minimal flat sidebar aesthetic.

Flatten sidebar item styling (smaller icons, tighter margins) to match

Notes' minimal aesthetic. Add hover-reveal (x) delete buttons on Views

and AI Generated list items. Extract delete logic into partial class

DataViewModel.Delete.cs with async reference search — on delete request,

the overlay now checks for cross-plugin entities referencing the dataset

via SDK SearchAsync and displays clickable navigation links before

confirming. Add DatasetReference model, wire IPrivStackSdk through

DataPlugin. Bump version to 1.20.0.
