feat: move Blueprint orchestration and Federation placement to Community tier (#1555)

* feat: move core Blueprint orchestration to Community tier

Blueprints CRUD, reconciliation, and drift modes are now available on
Community. Pin remains Admiral-only via Federation placement controls.

* feat: move Federation placement controls to Community tier

Remove requirePaid from cordon, uncordon, and blueprint pin routes. Ungate the Federation tab and gate cordon UI on node:manage only. Update licensing and fleet docs for the new tier split.
