new version of HA returns arrays instead of single

[vzabavnov]

I don't use code generator very often because I use my own strongly types library, but I use to check if I messed up with something. juts recently I found Code generation doesn't work during deserialization error. I found what cause the issue: Json returned from HA returns arrays instead of single item as it was previously:

"selector": {
  "area": {
    "device": [
      {
        "integration": "zwave_js"
      },
    ]
    "multiple": true
  }
}

the device now is an array. there are few other places where selectors have arrays instead of single one.
in addition, I found new element on the device, the filter:

"selector": {
            "device": {
              "filter": [
                {
                  "integration": "zwave_js"
                }
              ],
              "multiple": true
            }
          }

I have a fix and checking if it works. at least now I am able to have fully generated entities

I have:

Core	2025.3.2
Supervisor	2025.03.2
Operating System	14.2
Frontend	20250306.0
