fix: replace Helm-based E2E deploy with kubectl apply

Browse Source 
The Helm chart deployment was consistently failing — the pod enters
CrashLoopBackOff despite identical kubectl manifests working. The Helm
chart also silently ignored extraVolumes/extraVolumeMounts (pnpm-style
keys not supported by the chart), meaning the plugin ConfigMap was
never actually mounted even when deploy appeared to succeed.

Replace with direct kubectl apply using a bash heredoc to render the
manifest with shell variable substitution. This removes the Helm
dependency, fixes the plugin volume mount, and uses the exact
configuration that was proven to work in the cluster.

Also adds explicit initialDelaySeconds/failureThreshold on readiness
and liveness probes to give Headlamp adequate startup time.

Note: .github/workflows/e2e.yaml still has a Setup Helm step that is
now unused — assigned to Hugh Hackman to remove.
