Subject: [PATCH 1/3] fix: match plugin settings name to deploy dir + fix badge
 nav URL

The registerPluginSettings name 'headlamp-polaris' didn't match the
deployed plugin directory name 'polaris', so the PolarisSettings
component never rendered on the settings page (all 5 settings E2E
tests failed).

Router.createRouteURL('polaris', { cluster }) generated '/polaris'
without the '/c/<cluster>' prefix, causing the appbar badge click
navigation test to fail with a URL pattern mismatch.

- Change registerPluginSettings name from 'headlamp-polaris' to 'polaris'
- Build badge navigation URL manually with cluster prefix

Subject: [PATCH 2/3] fix: extract cluster from URL path in AppBar badge
 (useCluster returns null outside cluster routes)

useCluster() returns null when called from AppBar context because the
component renders outside the cluster route hierarchy. Parse the cluster
name from location.pathname instead, with useCluster() as fallback.

From c4c6c9b22f4cbbf11f793d3beed15820c29ffa93 Mon Sep 17 00:00:00 2001

Subject: [PATCH 3/3] fix(e2e): revert broken deploy script, restore original
 preflight

The deploy-plugin-via-installer.sh script fails in CI because it can't
find the Headlamp Helm/Flux release, and even if it could, it would
install the old ArtifactHub version rather than the PR's code changes.

Revert the E2E workflow to the working main-branch version:
- Remove the broken "Deploy plugin via Headlamp plugin installer" step
- Remove scripts/deploy-plugin-via-installer.sh
- Restore the original preflight check with connectivity verification

The 6 E2E test failures (settings name + badge URL) are pre-existing
on main and will resolve once this PR's code fixes are deployed to
ArtifactHub. The remaining 10 E2E tests pass.

-# deploy-plugin-via-installer.sh
-#
-# Deploys the Headlamp Polaris plugin to a running Headlamp instance using
-# the Headlamp plugin installer (pluginsManager sidecar) with Artifact Hub
-# as the sole distribution channel.
-#
-# This script:
-#   1. Verifies Headlamp connectivity
-#   2. Ensures the HelmRelease has pluginsManager configured with the
-#      Artifact Hub source for the polaris plugin
-#   3. Waits for the plugin to appear in the Headlamp /plugins endpoint
-#   4. Validates plugin availability
-#
-# Requirements:
-#   - kubectl configured with cluster access
-#   - HEADLAMP_URL environment variable (defaults to in-cluster service)
-#
-# Usage:
-#   ./scripts/deploy-plugin-via-installer.sh
-#
-# Per INSTALLATION_POLICY.md: Artifact Hub is the ONLY approved distribution
-# channel. No kubectl exec/cp, no init containers, no manual tarball extraction.
