Phase 3a: shadcn init + Home/Case List view

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. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
