Phase 2.2: Node Parameter Editing & Inline Configuration

This phase introduces the ability to configure nodes directly on the canvas.
Users should be able to edit node parameters inline without leaving the workflow editor.
Configuration should be dynamically generated based on the node type and its defined plugin schema.

Deliverable

• Nodes can be configured inline with automatically generated forms.
• Parameter changes are reflected in real-time on the canvas.
• Workflow draft updates are persisted to Drupal via REST/JSON:API.
• Validation prevents execution of incomplete or invalid nodes.
