Two additions to pumpingStation:
1. _controlLevelBased now calls _applyMachineGroupLevelControl in
addition to _applyMachineLevelControl when the basin is filling
above startLevel. Previously only direct-child machines received
the level-based percent-control signal; in a hierarchical topology
(PS → MGC → pumps) the machines sit under MGC and PS.machines is
empty, so the level control never reached them.
2. New 'Qd' input topic + forwardDemandToChildren() method. When PS
is in 'manual' mode (matching the pattern from rotatingMachine's
virtualControl), operator demand from a dashboard slider is forwarded
to all child machine groups and direct machines. When PS is in any
other mode (levelbased, flowbased, etc.), the Qd msg is silently
dropped with a debug log so the automatic control isn't overridden.
No breaking changes — existing flows that don't send 'Qd' are unaffected,
and _controlLevelBased's additional call to machineGroupLevelControl
is a no-op when no machine groups are registered.
