Axen_heatpump: improvements based on PR #2787

- use inlet rather than ambient temperature for climate current temperature
- decouple water heater operation mode from the switch
- add fault_flag to problem sensor
- mark less interesting sensors as hidden by default

Other sensors above dp 128 do not show in the log, and there are a lot
of them, often difficult to clearly differentiate from others, so were
not added. The original issue #2561 has all the details.
