Rename current_consumption to power

- Note: This is a breaking change.
- Fix: Rename `current_consumption` to `power` in energy modules, to deconflict and clarify.
- Fix: Report `0` instead of `None` for current when current is zero.
- Fix: Report `0` instead of `None` for voltage when voltage is zero (not that this was possible to see).
