(optional) The gRPC server
These servers are shut down gracefully by calling some kind of Stop or Shutdown function from main.go after backgroundCtx is canceled, which is done when the signal receives an os.Interupt (Ctrl-c) signal.

Payment tracking routines
Webhook dispatching routines
These are also canceled by canceling the backgroundCtx context. The waitgroup waits until all processes are finished before the program is exited.
