Replace usage of connect with useSelector() and useDispatch()

Update the code and tests to get rid of the Internal export pattern. Example:
Before:

export default connect(editableFieldSelector, {
  onEdit: openForm,
  onCancel: closeForm,
})(EditableField);

After:

const EditableField = (props) => {
  const dispatch = useDispatch();
  const onEdit = (name) => dispatch(openForm(name));
  const onCancel = (name) => dispatch(closeForm(name));
...
export default EditableField

Once the HOCs (connect) are replaced with hooks, if it's necessary to mock redux state in tests, convert the tests to use initializeMocks from src/testUtils.tsx and pass in initialState to initializeMocks. Or useconst { reduxStore } = initializeMocks();and dispatch changes to the redux store.
