/**
 * @file mod_mlat.c
 * @brief Multilateration Scanner Module (BLE + WiFi)
 *
 * This module turns an ESP32 into an RSSI scanner for multilateration.
 * Supports both BLE and WiFi modes, switchable at runtime from C2.
 * Position is configured from C2, and RSSI readings are sent back via TCP.
 *
 * Supports two coordinate systems:
 *   - GPS (lat/lon in degrees) for outdoor tracking with real maps
 *   - Local (x/y in meters) for indoor tracking with floor plans
 *
 * Commands:
 *   mlat config gps <lat> <lon>    - Set GPS position (degrees)
 *   mlat config local <x> <y>      - Set local position (meters)
 *   mlat config <lat> <lon>        - Backward compat: GPS mode
 *   mlat mode <ble|wifi>           - Set scanning mode
 *   mlat start <mac>               - Start scanning for target MAC
 *   mlat stop                      - Stop scanning
 *   mlat status                    - Show current config and state
 *
 * Data format sent to C2:
 *   MLAT:G;<lat>;<lon>;<rssi>      - GPS coordinates
 *   MLAT:L;<x>;<y>;<rssi>          - Local coordinates (meters)
