Launch mobile setup dialog upon clicking out-of-credits notification.

Upon detecting an out-of-credits scenario on the cellular connection, a
notification is shown to inform the user. Clicking the notification
currently launches the network settings page, which isn't obvious to the
user what they should do next. Instead, this CL changes that by
launching the mobile setup dialog, which brings the user to the online
payment portal to refill the data plan if needed.

      launches the mobile setup dialog.
