Add support Thermann R290 heat pump (#4165)

* Add Thermann R290 heat pump water heater config

Introduces a new device configuration for the Thermann R290 heat pump water heater, including support for water heater controls, diagnostic sensors, and various temperature and operational sensors.

* Remove icon fields from dps entries

Deleted the 'icon' attributes from DPS entries due to failing tests

* Update entity names in Thermann R290 config

Renamed entity fields to use snake_case: 'Operation mode' to 'operation_mode', 'Set temperature' to 'temperature', and 'Current temperature' to 'current_temperature' for consistency and improved integration.

* Update entity names in Thermann R290 device config

Renamed 'Diagnostic sensor' to 'sensor' and 'Fault Code' to 'fault_code' in the Thermann R290 heat pump water heater YAML configuration

* feat (thermann_r290_waterheater): rename and tidy

- rename file to have less components and match naming convention
- split power out so it can be switched
- use only valid operation modes
- use translations where available
