Parametric editor redesign.

[kamilmadejek]

This PR introduces a major redesign for configurable editor (see screenshots below).

Expandable sections have been replaced by top-level tabs and hierarchical tree structure of dynamically generated input controls. The new UI is designed to look and feel more modern and clear.

---

The new editor UI has been implemented for all the Nephio-specific resources, whose editors had been implemented using the configurable editor:

• req.nephio.org/v1alpha1/Capacity
• infra.nephio.org/v1alpha1/WorkloadCluster
• infra.nephio.org/v1alpha1/Network
• infra.nephio.org/v1alpha1/Token

Remaining editors, which are not implemented using the configurable editor, are intact and still functional using "legacy" UI. This enables us to migrate to a new design in an incremental manner.

---

Testing (on uitests environment, credentials available per request):

• Revision with WorkloadCluster, Capacity and Network parametric editors
• Revision with Token parametric editor
