fix: balance internal commodity nodes on power flows, not stock-side terms

A device can sit in both a commodity balance group (via its commodity) and
a shared-stock group (via its state-of-charge sensor), e.g. a steamer that
discharges a heat buffer to produce steam. Its derivative efficiencies and
stock delta (e.g. the buffer's soc-usage losses assigned to it) describe
the stock-side conversion and must not leak into the commodity balance:
what crosses the node is the device's power flow (ems_power).

Found while running the Sappi factory scenario, where the heat buffer's
soc-usage drain was distorting the steam balance.
