test(archief-assistent): add Playwright E2E test suite

- Add chat.spec.ts for RAG query testing
- Add count-queries.spec.ts for aggregation validation
- Add map-panel.spec.ts for geographic feature testing
- Add cache.spec.ts for response caching verification
- Add auth.setup.ts for authentication handling
- Configure playwright.config.ts for multi-browser testing
- Tests run against production archief.support
