### Describe the bug

When using [GetOutputList](https://github.com/obsproject/obs-websocket/blob/5.4.2/docs/generated/protocol.md#getoutputlist) to get a list of available outputs, NDI Preview Output shows up in the list whether or not it is enabled in Tools -> NDI Output Settings but NDI Main Output only shows up in the result of GetSourceList only if it is enabled in Tools -> NDI Output Settings.

![image](https://github.com/user-attachments/assets/d1d79f46-9cb8-4f22-9464-5195ae5d5772)
With the above settings, GetOutputList result is the following:
```json
{
  "outputs": [
    {
      "outputActive": false,
      "outputFlags": {
        "OBS_OUTPUT_AUDIO": true,
        "OBS_OUTPUT_ENCODED": true,
        "OBS_OUTPUT_MULTI_TRACK": true,
        "OBS_OUTPUT_SERVICE": false,
        "OBS_OUTPUT_VIDEO": true
      },
      "outputHeight": 0,
      "outputKind": "ffmpeg_muxer",
      "outputName": "simple_file_output",
      "outputWidth": 0
    },
    {

      "outputFlags": {

      },
      "outputHeight": 1080,
      "outputKind": "virtualcam_output",
      "outputName": "virtualcam_output",
      "outputWidth": 1920
    },
    {
      "outputActive": false,
      "outputFlags": {
        "OBS_OUTPUT_AUDIO": true,
        "OBS_OUTPUT_ENCODED": false,
        "OBS_OUTPUT_MULTI_TRACK": false,

        "OBS_OUTPUT_VIDEO": true
      },
      "outputHeight": 1080,
      "outputKind": "ndi_output",
      "outputName": "NDI Preview Output",
      "outputWidth": 1920
    }
  ]
}
```


And with the following settings:
![image](https://github.com/user-attachments/assets/5ec281a9-1701-475c-be39-56c762c3d055)
GetOutputList result is the following:

      "outputHeight": 1080,

      "outputName": "NDI Main Output",
      "outputWidth": 1920
    },
    {
      "outputActive": false,
      "outputFlags": {
        "OBS_OUTPUT_AUDIO": true,

      "outputHeight": 1080,
      "outputKind": "ndi_output",
      "outputName": "NDI Preview Output",
      "outputWidth": 1920
    }
  ]
}
```

As you can see, even when NDI Preview Output is disabled throug NDI Output Settings, it still shows up as an available output to OBS. This means its settings and status can be changed through obs-websocket when it is disabled. This is not the case with NDI Main Output as it is currently required that it be enabled in NDI Output Settings to be able to manipulate it through obs-websocket.

According to the logs, NDI Preview Output is getting created at startup even if it is disabled in NDI Output Settings:

### Steps to reproduce the problem

1. Go to NDI Output Settings and disable both Main output and Preview Output.
2. Call GetOutputList to get the list of available outputs. Main Output will not be in the list while Preview Output will.
3. Go to NDI Output Settings and enable Main Output.
4. Call GetOutputList to get the list of available outputs. Main Output will now be listed.

### Expected behavior

Main Output is expected to be created at startup so it can be manipulated through OBS whether or not it is active.
