/**
 * DevAmsTray - Represents a single filament tray/slot in an AMS unit or virtual tray.
 *
 * Data Population:
 * ================
 * This class is used in two contexts with different population paths:
 *
 * 1. AMS Trays (within DevFilaSystem):
 *    NetworkAgent → MachineObject::parse_json() → DevFilaSystemParser::ParseV1_0()
 *
 * 2. Virtual Trays (MachineObject::vt_slot for external/manual filament):
 *    NetworkAgent → MachineObject::parse_json() → MachineObject::parse_vt_tray()
 *
 * Key Fields Used by build_filament_ams_list():
 * - setting_id: Filament preset identifier (tray_info_idx from printer)
 * - tag_uid: RFID tag unique ID for identifying filament spools
 * - m_fila_type: Filament material type (e.g., "PLA", "ABS", "PETG")
 * - color: Hex color string without '#' prefix (e.g., "FF0000")
 * - cols: Multi-color component list for gradient/multi-color filaments
 * - ctype: Color type indicator
 * - is_exists: Whether filament is currently loaded in the tray

 * Key Properties:
 * - m_ams_id: Unique identifier for this AMS unit (string, typically "0", "1", etc.)

 * - AMS (type 1): Standard 4-slot AMS with humidity control
 * - AMS_LITE (type 2): Simplified version
 * - N3F/N3S (types 3,4): Newer variants with different humidity/drying support

/**
 * DevFilaSystem - Central manager for all AMS-related data on a printer.
 *
 * This class owns and manages the hierarchy of AMS units (DevAms) and their trays (DevAmsTray).
 * It provides the primary interface for querying filament/AMS state used by the GUI.
 *
 * Data Flow Architecture:
 * =======================
 *   Printer Device (sends status via MQTT/LAN)
 *       ↓
 *   NetworkAgent (receives JSON, invokes registered callbacks)
 *       ↓
 *   MachineObject::parse_json() (delegates to DevFilaSystemParser)
 *       ↓
 *   DevFilaSystemParser::ParseV1_0() (populates this DevFilaSystem instance)
 *       ↓
 *   GUI functions like build_filament_ams_list() read from here
 *
 * Key Methods:
 * - GetAmsList(): Returns map of all AMS units (ams_id -> DevAms*)
 * - GetAmsTray(): Retrieves specific tray by AMS ID and tray ID
 * - HasAms(): Checks if any AMS units are connected
 *
 * Ownership:
 * - Owned by MachineObject (m_fila_system member)
 * - Owns all DevAms instances which in turn own DevAmsTray instances
 *
 * Note: This class does NOT directly communicate with NetworkAgent.
 * It is a passive data store populated by the parsing layer.
