Tracks the gpustack identity-consolidation effort: the unified
``principals`` table's URL-safe identifier column was renamed
``slug`` → ``name`` (with the legacy display ``name`` → ``display_name``).
The enterprise plugin's persisted org caches (``organizationList``,
``allOrganizations`` in localStorage) now write ``name`` instead of
``slug`` on each Organization row.
``getCurrentOrgNamespace`` reads those caches to compose the k8s
namespace (``gpustack-{name}``) for GPU-instance / storage CRDs.
Updated to read ``item.name`` so namespace resolution stays in sync
with what the enterprise plugin writes — otherwise every gpu-service
write would fall through to ``gpustack-default`` even when the user
has an Org context.
Stale ``slug`` references in surrounding comments also retitled to
``name`` to avoid divergence between code and prose. The namespace
format itself (``gpustack-{...}``) is unchanged — only the column it
sources is.
The legacy ``getCurrentOrganizationId`` helper returned the raw numeric
org id from localStorage, which the GPU-service / storage call sites
then used as the K8s namespace path segment — producing requests like
``/v2/clusters/1/proxy/.../namespaces/5/instances``. The backend
creates a namespace named ``gpustack-{slug}`` (matching
``get_namespace_name``), so the request hit a namespace that doesn't
exist.
Replace the helper with ``getCurrentOrgNamespace`` that:
- prefers the Org the caller is acting under (numeric
``currentOrganizationId`` from localStorage, slug looked up in the
persisted ``organizationList`` or ``allOrganizations`` cache);
- falls back to the selected cluster's owner Org slug for the admin
"All" view, where there is no explicit Org context but the resource
still has to land in some Org's namespace — call sites pass
``currentCluster?.owner_principal_id`` through;
- falls back to ``gpustack-default`` only if neither path resolves a
slug (first load before any cache hydrates, etc.).
``ClusterListItem`` is widened with the optional ``owner_principal_id``
field so TypeScript accepts the fallback argument; the backend has
been returning it via ``ClusterPublic`` all along.
