* Add current heater power % to job status
* Add show_heater_power config option and move update_temp()s to ScreenPanel
* Add the option to the UI config instead of the docs
* Prefer extra items on job_status over the power
There is not a lot of space, it's a trade off, and people will likely prefer extra_items
* Remove the comma, none of the other buttons have it
* job_status: inherit the parent config
* screen: create reload_panels to avoid some service restarts
* extrude: fix power breaking multi-extruder setups
* main and temp: remove degrees char from the table
* main and temp: revert removal of the header
