Pull Request Overview

This PR adds support for the new enableSystemIdentityProvider flag in the control plane spec, surfaces it through the ListControlPlanes JQ query, and updates the UI logic (and tests) so that the Connect button is enabled only when the system IdP is turned on.

• Extend ControlPlaneType.spec with authentication.enableSystemIdentityProvider and adjust the JQ extractor
• Update the test helper in controlPlanes.spec.ts to include the new authentication field
• Simplify ControlPlaneCard to read the flag directly from the passed-in spec instead of fetching a separate resource
