feat: restore cluster detail surface, gate cluster-list name link via plugin

The "chore: hide cluster detail" change had commented out both the
cluster-detail route and the cluster name link in the list. The
detail page component still ships in the OSS tree, so reach is
restored but the link is plugin-gated rather than unconditional:
plain OSS renders the name as a span; with a registered
`clusterDetail.linkableName` flag the name turns into a
`Typography.Link` that fires the parent's existing `onCellClick`
(which navigates to the detail route).

Detail tabs adjustments for the in-cluster context:
- Drop the Deployments tab (deployments are managed from the
  top-level Models page; the detail view is scoped to a single
  cluster's hardware).
- `WorkerList` and `GPUList` accept an optional `clusterId`. When
  set, the list pins `cluster_id` in its query and hides the
  cluster-filter dropdown so the user can't scope away from the
  cluster they're inside.

`clusterDetail.extraTabs(clusterId, intl)` exposes a plugin slot
that appends additional tab items — used by the enterprise plugin
to inject per-cluster Access / Quotas surfaces. No-op without a
plugin.
