refactor: improve graph property update mechanism

- Move graph data and UI state update logic into store
- Ensure all property updates trigger PropertiesView refresh
- Add graphDataVersion dependency to PropertiesView
- Follow React best practices by avoiding direct UI state modification in utility functions
- Fix issue where non-entity_id property changes weren't reflected in UI
