Fix rack order race condition allowing slots/power to exceed DC limits
CI / build-and-push (push) Successful in 47s

Rapid clicks on order rack bypassed capacity checks because usedSlots
and usedPowerKW were only updated during the tick. Now both the store
action and UI compute slot/power usage live from racks + pipeline,
so each order immediately reflects in the next check.
