Update MQTT preferences to support configurable WiFi power save mode

- Added conditional compilation for WiFi power save settings in setMQTTPrefsDefaults.
- Updated platformio.ini files across multiple variants to define MQTT_WIFI_POWER_SAVE_DEFAULT and related configurations.
- Set default WiFi power save mode to 1 (none) when not explicitly defined, enhancing flexibility for different hardware setups.
