feat(10.2-02): add structured error returns to all 7 sub-workflows

- Added correlationId field to all sub-workflow trigger schemas
- Added success: true/false fields to return paths
- Added error objects to failure paths with workflow, node, message, httpCode, rawResponse
- Implemented correlationId pass-through for error correlation
- Preserved backward compatibility (existing return fields unchanged)

Modified sub-workflows:
- n8n-actions.json: 3 Format Result nodes with full error objects
- n8n-update.json: Pull/Create/Start error paths with error objects
- n8n-logs.json: Added correlationId pass-through
- n8n-batch-ui.json: Added correlationId to trigger
- n8n-status.json: Added correlationId to trigger
- n8n-confirmation.json: Added correlationId pass-through to stop action
- n8n-matching.json: Added correlationId to trigger

All sub-workflows now return structured error objects on failures for main workflow error ring buffer capture.
