Fix auto open details

[kmcginnes]

Description

Fixes the auto open details feature by calling the open action during the selection callback.

I also made a combined event for when selection changes in the graph. So nodes & edges come together in a single event, simplifying the auto open logic and removing a useEffect.

Also, removed an unused prop from NodeDetails that was for the old search UI.

Validation

• Verified selection behavior with sidebar open and closed
• Verified table row selection mirrors graph selection
