Add Varpoolfaye 5kW Pool Heat Pump support (#5099)

* Add Varpoolfaye 5kW Electric Pool Heat Pump device profile

* Remove unreliable DP 101 compressor sensor from Varpoolfaye profile

* Address review feedback: use generic name, replace preset_mode with hidden mode

- Rename top-level name to generic "Pool heat pump"
- Update model to "Pool Mini"
- Replace preset_mode with hidden mode dp, expose only via hvac_mode

* fix(varpoolfaye_5kw_pool_heatpump): remove extra mapping

Removed mapping for mode values in varpoolfaye heatpump.
