fix: use official Headlamp API instead of internal paths

The plugin was importing from internal Headlamp paths like
'@kinvolk/headlamp-plugin/lib/lib/k8s/cluster' instead of using the
official public API '@kinvolk/headlamp-plugin/lib'.

This caused the plugin to fail loading in the browser with:
"TypeError: undefined is not an object (evaluating 'Ot.KubeObject')"

Changes:
- Updated imports to use K8s.cluster and ApiProxy from main export
- Added vite.config.js with custom globals (now obsolete with this fix)
- Moved node-forge to dependencies for proper bundling

The plugin now uses only the official documented Headlamp plugin API.

Fixes: #[issue number if exists]
