[cookbook] Fix power_meter action and sensor ID references

- Change `pulse_counter.set_total_pulses` to `pulse_meter.set_total_pulses`
  (the cookbook uses pulse_meter, not pulse_counter)
- Change `power_id: sensor_energy_pulse_meter` to `power_id: sensor_pulse_meter`
  (matches the sensor ID defined earlier in the cookbook)
