Fix getNamespaces() to skip cluster-scoped resources (Namespace: "")
that caused Router.createRouteURL to throw TypeError on the Namespaces
page. Add Playwright E2E smoke tests with Authentik OIDC auth for CI
and K8s token fallback for local dev. Add Gitea Actions E2E workflow,
vitest unit test infrastructure, and test-utils fixtures.

Merge Overview and Full Audit into a single dashboard page that always
shows the skipped check count. Fix namespace link 404s by using
Headlamp's Link component (which generates cluster-prefixed URLs)
instead of raw react-router-dom Link. Add vitest unit tests for all
polaris.ts utility functions.
