feat: tease enterprise multi-tenancy and API key controls in OSS

Add an Organizations menu entry (admin-only) that routes to an upsell
page explaining the multi-tenancy module, and surface disabled
IP Access Control / Quota Limit items in the API Key dropdown with a
tooltip pointing at the enterprise edition. Both placeholders are
shadowed by the enterprise plugin at build time: the route merger
removes the OSS Organizations entry by name, and the dropdown skips
each placeholder when the same key is contributed via configActions.
