SAFETY-83: peak guard outranks the maintenance drain at N=1

At N=1 the drain is the site SET at P_MAINTENANCE (60), so the peak floor
(P_PEAK, 50) was not applied and the house imported what the drain left.
Where the floor asks for more than the drain rate, main.py now refiles the
peak claim at P_MAINTENANCE, so it wins; safety SETs still park everything.
Nothing else changes: safety78_identity --diff against 35cdffe changes only
cycles where the guard wanted more than the drain; N=2 is byte-identical.
