Reverts the canonical half of 8216480 (which set BOTH canonical and output
to m³/h) back to the platform-wide m³/s convention. Canonical m³/s is what
every cross-node consumer assumes — MGC percent→flow demand interpolation,
the volume integrator (flow × dt), and physics-sanity balances. Changing the
canonical basis to m³/h silently scaled those by 3600×.
Output flow / netFlowRate stay m³/h so telemetry and dashboard series remain
on the same axis as the rest of the pump group (verified slice #47). The
m³/s→m³/h conversion now happens at the output boundary only, never on the
internal integrator basis.
No smoothing/hysteresis added for the PS→MGC demand hunting: per design
review that belongs in a dedicated intermediate node (e.g. a PID), not in
the pumpingStation or machineGroupControl control path.
