Optimize the MQTT code (Shelly 4 Pro)

Configuration
4

I reduced it to two automations, one publishes to Domoticz and the other receives from it. It’s possible to combine them but not completely necessary.

The following two examples are not tested so they may require a few adjustments.

- id: 'publish_to_dz'
  alias: Publish to DZ
