🧹 [Code Health] Remove unused RefObject type import

[mbayue]

🎯 What: Removed unused RefObject type import from react and updated ForceGraphExportOptions to directly use React.RefObject.
💡 Why: Cleans up the code and maintains consistent naming, as other React features were already being utilized off the React namespace (or implicitly).
✅ Verification: Ran linters, type checks, and the full test suite which passed successfully (the failing tests are identical to those failing on the master branch).
✨ Result: A small code health improvement that increases maintainability.
