feat: Add vertical remote plugin collection support (#23584)

- Adds an explicit vertical marketplace kind for plugin/list that
fail-open fetches collection=vertical only when full remote plugins are
disabled.

- Renames the global remote marketplace/cache identity to
openai-curated-remote and materializes remote installs with backend
release versions and app manifests.
