support for modern flames orion device lights/flame only mode (#5264)

* changed off to cool for lights/flame only mode

* modified:   modernflames_orion_fireplace.yaml
  move climate from boolean switch to pure hvac_mode with preset
  rename eco to low heat, boost to high heat
  added boolean switch for power control

* fix(modernflames_orion_fireplace): remove whitespace and unnecessary scaling

- trim whitespace to solve lint error
- remove scaling of brightness, as it can auto scale when range is given
