Hide team invite step on progress widget for single-user plans

Injects ISubscriptionService into DashboardController and calls
GetUserCountAsync to check the plan's MaxUsers limit. When MaxUsers == 1
the "Bring your crew in" step is omitted from the progress widget entirely,
so solo-plan users aren't prompted to do something their subscription
doesn't allow. Plans with MaxUsers > 1 or unlimited (-1) show the step
as before.
