Adds read support for DHW sensor selection (byte 11, bits 7-8) as a new topic (TOP143), and a SetDHWSensorSelection command to switch between Top and Center tank sensors via MQTT. This enables automation scenarios where the active DHW sensor can be toggled programmatically (e.g., alternating between top and center readings for monitoring both tank positions). Applicable to K/L series All-In-One units only. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
DHW_Sensor_Selection) that decodes byte 11, bits 7-8, reporting which DHW tank sensor is active (0 = Top, 1 = Center)MQTT-Topics.mdandProtocolByteDecrypt.mddocumentation accordinglyThis is applicable to K/L series All-In-One units only, where the DHW tank has both a top and center temperature sensor. The byte 11 bits 7-8 layout was already documented in
ProtocolByteDecrypt.mdbut had no corresponding read topic or SET command.Changes
