refactor: always set temperature to ID 1

* added option to always send the current and target indoor temp, even if the current heating mode doesnt officially need it. This is a direct fix for WeHeat heatpumps which seem to require it.

* add option to AlwaysSendIndoorTemp and rename NativeHeatingControl to
NativeOTC.

Updated locals and settings page.

* change minor order
