(Screenshots, videos, or GIFs, if applicable)

Refactiored InfoModal.test.utils.js to TypeScript (InfoModal.test.utils.tsx) and removed all implicit any types.

• Typed renderWithMockStore parameters: component: ReactElement, initialState: InfoModalMockState, store: Store<InfoModalMockState>.
• Added a local InfoModalMockState interface for the mock store shape (options.app.errorMessage). It's test-only, so it isn't added to the shared types.
• Replaced createStore(modalReducer, initialState) with legacy_createStore and a pass-through reducer. The mock state isn't a ModalState, so using modalReducer would need an unsafe cast. At runtime it only returned the state unchanged, so behavior is the same.
  (legacy_createStore avoids the Redux 5 deprecation warning without adding @reduxjs/toolkit.)
• No changes to InfoModal.test.tsx; the import path resolves to the new file.
