Extract the fan peak-tracking into observedPeakStore (observe max under load, hold >= minHold to reject spikes, round, persist JSON) and add a second instance for PSU draw (psu-observation.json, keyed by PSU ordinal). Fed from samplePSUPower like fans are from sampleFanSpeeds, so any full-load run refines it — the Fan Ceiling Check (which also samples PSU power at a slow cadence off its loop and writes psu_<i>_peak_w), a burn, thermal cycling, and the 5s web metrics collector. /topo PSU cards now scale the load fill by wattage_w when the BMC reports it, else by the observed peak draw — marked "~N% load". This MSI stand's BMC gives only instantaneous input power, so the observed peak is the only capacity figure available. Fan behaviour is unchanged (tests exercise updateFanObservation / estimateFanDutyCyclePctFromObservation / ResolveFanMaxRPM through the new store).
