Each StepPlate on the Progress tab now shows a step's energy use in
Wh - live and growing while it's the active step, frozen at its final
total once finished, blank before it's ever been reached.
Integrated server-side from the heater's own live effective power
(pot.get_power(), already fed from heater.power_eff - see server/
brewpi.py's wiring), since actual energy used can't be predicted from
the forecast like the timing/temperature fields are, only measured as
it happens. Banked into energy_by_step on every genuine step
transition (on_step_changed(), keyed off the same index-change check
used for the ramp->hold phase switch), including the final transition
to DONE; reset on every fresh Load.
