* feat(mcs350): add Teploluxe MCS350 thermostat

Add new thermostat
products:
  - id: "tfmfbr341u0tx3fb"
    manufacturer: Teplolux
    model: Teploluxe MCS350 Thermostat

* fix(mcs350): remove invalid values at teploluxe_mcs350.yaml

* fix(mcs350): remove trailing spaces

* fix(mcs350): correct naming

* fix(mcs350): correct entities naming

* fix(mcs350): add power scaling

* fix(mcs350): correct validaton

* Update thermostat YAML with new temperature mappings

- Standardize naming to be consistent with other thermostats.
- use sensor setting to dynamically select whether floor or air temperature is shown in the main climate entity.

* Abbreviate ar_temp to avoid false positive on similarity check

- air_temperature is too similar to standard attributes, so falsely detected as a possible typo.
Change the name to avoid that. Since it is a hidden attribute, an abbreviated name is fine.
