Implement the Applications List view for headlamp-argocd-plugin (PRI-189).
- Add src/components/ApplicationsList.tsx with table of all ArgoCD Applications
showing: app name, namespace, project, health status, sync status,
target revision, and last synced time
- Health/sync status badges using ArgoCD color conventions
- Filter controls: health dropdown, sync dropdown, project dropdown
- Friendly "ArgoCD not detected" error state when ArgoCD is unreachable
- Add src/api/argocd.ts with ArgoCD API types (Application, ApplicationsList)
- Add unit tests in src/__tests__/ApplicationsList.test.tsx:
- Pure function tests for healthStatusToColor and syncStatusToColor
- Filter logic unit tests
- Component smoke tests (loading, error, data, empty states)
- Replace stub view in src/index.tsx with ApplicationsList component
