/**
 * @file meshx_model_power_level.hpp
 * @brief Implementation of Generic Power Level Model for MeshX
 *
 * This file contains the implementation of the Generic Power Level model,
 * which provides standard Power Level model functionality in the MeshX BLE mesh framework.
 *
 * Key Features:
 * - Implements Bluetooth SIG-defined Generic Power Level model
 * - Inherits from meshXClientModel, meshXServerModel templates
 * - Provides standard Power Level control operations (GET, SET, LAST, DEFAULT, RANGE)
 * - Integrates with MeshX transmission control
