Fix camera jump when left-clicking empty space in graph

- Remove context menu from left-click to prevent rapid show/hide cycles
- Context menu now only appears on right-click as intended
- Fix auto-fit useEffect dependency to prevent unnecessary camera movements
- Left-click on empty space now only closes dialogs and clears selections
- Eliminates disruptive camera jumps during normal interaction
