New dynamic route /cases/[caseNumber] wired to the FastAPI details
endpoint, using Next 16's async params pattern with React's use()
hook. TanStack Query handles 5s refetchInterval so the page
self-updates during long-running processing without manual polling.
New components: CaseHeader (breadcrumb + meta), WorkflowTimeline
(5-phase RTL pipeline view), DocumentsPanel (categorized list).
Tabs split overview/documents/actions.

Initialize shadcn/ui (radix-nova preset) and wire its semantic tokens
to the editorial navy/cream/gold palette so primitives inherit the
judicial voice without per-component overrides.
Replace the Phase 2 live-probe with a real dashboard: KPI tiles,
conic-gradient status donut (ported from the vanilla renderHero),
and a TanStack Table cases list with search + sort. Add useCase(n)
hook with 5s staleTime/refetchInterval to replace the old manual
polling loop when Case Detail ships next.
