Add new frontend pages for the multi-tenant OCDP platform:
- Charts page (/charts): Browse Harbor OCI registries to list Helm chart repositories
and versions, with deploy modal to launch charts on selected clusters
- Monitoring page (/monitoring): Display cluster metrics (CPU/Memory/GPU usage)
and per-node details with resource utilization bars
- Chart References page (/chart-references): CRUD for chart metadata references
- Values Templates page (/templates): CRUD for Helm values templates with version
history and rollback support
- Sidebar: Add Charts navigation, update Storage and Templates links
- api.ts: Add all API client functions (clusterApi, registryApi, instanceApi,
monitoringApi, storageApi, chartReferenceApi, valuesTemplateApi,
workspaceApi, userApi) with full TypeScript types
Note: deploy flow and values template rollback not yet end-to-end tested.
