Broker sessions rest while nothing needs them

A firm's client used to stay logged in around the clock, renewing on a fixed
timer overnight and at weekends. Now, once a firm has nothing open, nothing
pending and nothing left to trade before its next session for a random
15–45 minutes, its client disconnects and the dashboard shows it Resting.
It logs back in a random 20–50 minutes before the next session opens, at a
check-in every 3–7 Central daytime hours, or at once when trading starts, a
manual leg, copy trade, manual order or AutoBuyer run needs it. Token
renewals fall at random points (Tradovate 15–45 min before expiry, TopstepX
every 45–150 min). Settings → Trading → Rest idle broker sessions
(session_rest) turns it off.
