After updating to the latest version of the Zaptec integration, the service call zaptec.limit_current fails both in Node-RED and directly from Home Assistant Developer Tools.

Actual behavior:
The service fails with the following error: HomeAssistantError: Limit current failed: '<=' not supported between instances of 'int' and 'NoneType'

Additional information:
This setup has worked reliably for over two years.
The error occurs even when calling the service directly from Developer Tools, without Node-RED.
In Developer Tools → States, the charger entity no longer shows a numeric max_current attribute — it appears to be null.
It seems this attribute might have been removed in the latest version, but the limit_current logic still expects it to be a number.

Home Assistant core version: 2025.8.1
