feat: Sprint 4 complete — frontend MVP (admin dashboard + member portal)

Shadboard starter-kit (Next.js 15 + React 19 + shadcn/ui + Tailwind 4)

Sprint 4.a — Admin Dashboard:
- Auth: NextAuth.js v5, login page, middleware, token rotation
- Dashboard: KPI cards, Recharts stock chart, quick actions
- Members: TanStack Table (search/sort/paginate), add/edit forms
- Distributions: multi-step form, real-time quota check, history
- Stock: batch management, recall dialog, bar chart
- Reports: monthly/member-list/recall, PDF/CSV download, preview

Sprint 4.b — Member Portal:
- Separate route group with top-nav layout (mobile-first)
- Quota dashboard with radial SVG progress indicators
- Distribution history with month filter
- Profile/settings with password change

Cross-cutting:
- i18n: German (default) + English via next-intl
- Dark + light mode (next-themes, user-togglable)
- Playwright E2E tests (6/6 green)
- Docker multi-stage build (node:22-alpine)
- API proxy via Next.js rewrites

Tech: Next.js 15.2.8, React 19, Tailwind 4, NextAuth v5,
TanStack Table, Recharts, Zod, React Hook Form, Playwright
