Add support for MQTT-based smart plugs that subscribe to external MQTT topics and extract power/energy data from JSON payloads. This enables integration with Zigbee2MQTT, Shelly, Tasmota discovery, and other MQTT-enabled energy monitoring devices. Features: - New "mqtt" plug type alongside tasmota and homeassistant - Subscribe to any MQTT topic with configurable JSON paths - Extract power, energy, and state values using dot notation - Optional multiplier for unit conversion (mW to W, etc.) - Monitor-only mode (no on/off control) with teal color scheme - Reuses existing MQTT broker settings from network configuration - Energy data included in statistics and per-print tracking - Full backup/restore support for MQTT plug configurations Closes #173
