Add reported_total_capacity_Wh and use it for SOLAX. Cleanup scaled values on webpage (#1002)

Browse source 
* Add reported_total_capacity_Wh and soh to SOLAX messages.
* Improve display of scaled values on webpage.
* Additionally also improve display of temperatures, cell voltages and combine voltage and current on one line.
* Refactor formatPowerValue function.
