Subject: feat(ui): Extract topology construction out of Sagas

This change updates the OpenDC frontend to perform the construction of
the topology directly in the reducers instead of performing the
mutations in Redux Sagas as side effects. This allows us to nicely map
actions to mutations in the reducers.
