fix: add scatterplots

Extract shared utilities (color functions, icon registry), replace hero
banners with compact PageHeader, add TrimesterSelector/ConfirmDialog/
Breadcrumb components, consolidate off-palette colors to design tokens,
convert AssessmentListView to table layout, compress ResultsView stats
into horizontal bar, and inline ClassFormView as a modal in ClassListView.
