Fix the commands that are sent from the simulator

This fixes the second issue in
US-JOET/base-camp#153 (comment)
by making the nodered consistent with
EVerest/everest-core@993a60c

- we pass in `ac` or `dc` as the energy type
- we add in the payment method, which we will plumb through in the next commit
- we change the mqtt toptic, also consistent with the commit above
