Fix auth form errors and redirects: Add React keys/useEffects for error rendering and scroll, Inertia::location in controllers for SPA navigation, extend RegistrationTest and add E2E. Update docs (changes/2025-10-02-registration-fixes.md, prp/13-backend-authentication.md). Add new UI components (accordion, carousel, progress, table, tabs), marketing/legal pages (Blog, Kontakt, Datenschutz, etc.), fonts, user migration (remove_name), views/css/package updates, seeders/factories.
