Display flow run outputs in Python script node editor

[Edwardvaneechoud]

Summary

This PR adds functionality to retrieve and display output artifacts (images, HTML, text) from the last flow execution in the Python script node editor. When a flow run completes, the frontend now automatically fetches display outputs and attaches them to the last notebook cell for visualization.

Key Changes

• Frontend (PythonScript.vue):

  • Added watch to monitor flow run completion via editorStore.isRunning
  • Implemented loadFlowRunDisplayOutputs() to fetch display outputs from the backend
  • Attaches display outputs to the last cell's output when flow execution completes
  • Integrated display output loading into the node data initialization flow

• Frontend API (node.api.ts):

  • Added getDisplayOutputs() method to retrieve display outputs from backend
  • Gracefully handles errors by returning empty array

• Backend Routes (routes.py):

  • Added /node/display_outputs GET endpoint to retrieve display outputs for a specific node
  • Validates flow and node existence before returning results

• Backend Models (flow_graph.py & flow_node/models.py):

  • Extended NodeResults class with display_outputs field to store output artifacts
  • Added logic to capture and store display outputs after kernel execution
  • Converts display output objects to serializable dictionaries for API response

Implementation Details

• Display outputs are stored on the node's results object during flow execution, making them available for retrieval after the run completes
• The frontend uses a watcher on editorStore.isRunning to detect when a flow run finishes and automatically refreshes both display outputs and artifacts
• Display outputs are attached to the last cell in the notebook, allowing users to see execution results directly in the editor
• Error handling is graceful—if display outputs cannot be retrieved, the operation fails silently without disrupting the user experience
