Fix Issue #3: Add delay after MQTT configuration before console settings

- Add 1-second delay after MQTT changes to allow device to process
- Only delays when MQTT settings were actually updated
- Prevents intermittent failures when applying console settings
- Device needs time to process MQTT reconnection before accepting new commands
