Replace the GPU Service switch (with the small "cannot be used for
model service" caption) with a two-card radio selector that makes the
choice between Model Service and GPU Service explicit at a glance.
- Render two cards styled to match the existing SwitchCard (same
border, radius, 12px/14px padding, and label/description typography)
so the selector blends in with the surrounding form fields.
- Underlying form state is unchanged: picking GPU Service still seeds
k8s_options.gpuInstanceOptions = {}, picking Model Service clears
it — so the static-address field, the EDIT-mode change watcher, and
the API payload all keep working as before.
- Align the GPU Service label with the top-level menu entry
(menu.gpuService) — drop "Instance" / "实例" from the card title
and the static access address label.
