fix: resolve 6 E2E failures — cluster URL prefix + settings registration

Two root causes for the remaining 6 E2E failures after PR #50:

1. AppBarScoreBadge: Router.createRouteURL('polaris') was called without
   the cluster parameter, producing '/polaris' instead of '/c/main/polaris'.
   Now uses K8s.useCluster() to pass the active cluster. (appbar.spec.ts:18)

2. Plugin settings: registerPluginSettings was called with 'polaris' but
   the package.json name is 'headlamp-polaris'. Headlamp matches settings
   registrations to the package name, so the component never rendered.
   (settings.spec.ts — all 5 tests)
