agessaman 498566e6c9 MQTT bridge: fix memory use, improve status reporting
- Main broker: only allocate _mqtt_client when custom broker configured
  (analyzer-only saves one PsychicMqttClient). Reconnect main broker after
  forced disconnect with 30s throttle; set last_attempt on disconnect so
  throttle applies and avoids reconnect storms on flaky WiFi.
- Analyzer clients: call disconnect() when WiFi transitions to disconnected
  so ESP-IDF frees MQTT buffers (it does not free on WiFi drop). Reduces
  fragmentation and Max drop after disconnect/reconnect cycles.
- get wifi.status: report WiFi uptime (Xd Xh Xm Xs) when WITH_MQTT_BRIDGE.
  Track connect time in bridge; backfill when already connected at first check.
- get mqtt.status: show msgs on/off, broker (connected/disconnected/n/a),
  analyzer US/EU (connected/disconnected/off), and queue count.

Note: PsychicMqttClient change (register event only on first client creation)
belongs in the library repo if committed separately.
