feat(web): typed error states + Playwright e2e for AVM v2 valuation

- Map 429/402/503 API errors to Vietnamese rate-limit, quota-exhausted, and model-unavailable banners on the /dashboard/valuation page. - Mark the error banner with role=alert and data-testid for a11y + testing. - Add e2e/web/valuation.spec.ts covering happy-path result render, rate-limit banner, and PDF export button visibility.
