Madimack pool heat pump

Proposed change Extends the Tuya integration to support pool heat pumps (device category QN) such as Madimack models. These devices use zone-based DPCode variants (e.g., SWITCH1, MODE1, TEMP_SET1) that were not previously handled by the climate entity. This change adds: - Support for zone-based DPCode variants throughout the climate entity - Fault detection binary sensors for pool heat pumps - Diagnostic temperature sensors (coil, exhaust, water temps, ambient, etc.) - Operational metric sensors (compressor strength, expansion valve, power) - Work mode select and child lock switch entities …
