Fix all event nodes to remain in place after dragging

Previously, only certain node types (person anchors, tag anchors, and 30040 events) would remain fixed after dragging, while other event types like kind 1 would snap back to their force-simulated positions.

Now all event nodes remain fixed in their dragged position, giving users full control over the graph layout. This applies to both regular force simulation and star visualization modes.

Changes:
- Modified setupDragHandlers to keep all nodes fixed after drag ends
- Modified createStarDragHandler to keep all nodes fixed after drag ends
- Removed special cases that only fixed certain node types
