Climate page - Performance & bug fix (#854)

* Climate page - Performance & bug fix

Performance improvement:
- Moved icon definition to TFT, so only buttons related to supported hvac modes will be updated and just icon color and link enabling is sent.
Bug fixing:
- Removed incorrect button name on buttons update
Others:
- Merged `set_climate_target_temp` into `set_climate` services
- Update current temperature when target temperature is updated

* Removed reference to `set_climate_target_temp`

Removed unused entry from blueprint.

* Removed service `set_climate_target_temp`

* Update `nspanel_eu`

- Set climate buttons on the TFT.
- Bump version to 3.3.2 (temporarily, to align with ESPHome and Blueprint)

* Update `nspanel_eu_code`

nspanel_esphome.yaml
