fix(api): refetch from server when online (stale-while-revalidate)

The Tier-2 rehydrated cache seeded fulfilled entries at startup, so RTKQ served stale data and never hit the network (manual metadata edits, etc. only appeared after clearing the cache). Enable refetchOnMountOrArgChange + refetchOnReconnect + refetchOnFocus and wire setupListeners, so the cached snapshot still shows instantly but the server silently revalidates it whenever reachable.
