fix(gpu-service): show global instance templates under custom scopes

The Instance Templates management page requested the `mine` list scope,
which drops admin-curated Global templates for non-admin callers. The
Inference Backend page uses the default scope and shows Global + own
rows, so the two pages behaved inconsistently.

Use the default scope on the templates page so Global templates are
visible alongside the caller's own, and gate Edit/Delete on the card so
Global rows a non-admin can't modify render read-only.
