Increase deposit sweep frequency

So far, deposit sweeps were supposed to happen every 48 hours. This frequency
was good for the early days of the system but starts to be insufficient
now, when a significant number of deposits land every day. To optimize
the deposit sweep process, we are increasing its frequency to 12 hours.
