fix: load agent for ws to support proxy during transfer

log errors when the transfer task faill

ex error we will be able to see when we run the transfer task:

console.error(e)
```
ProviderTransferError
    at WebSocket.<anonymous> (/builds/web/cms/node_modules/
    @strapi/data-transfer/dist/strapi/providers/utils.js:158:20)
    at Object.onceWrapper (node:events:639:26)
    at WebSocket.emit (node:events:524:28)

    at ClientRequest.<anonymous> (/builds/web/cms/node_modules/
    ws/lib/websocket.js:880:5)
    at ClientRequest.emit (node:events:524:28)
    at ClientRequest.emit (node:domain:489:12)
    at emitErrorEvent (node:_http_client:101:11)
    at TLSSocket.socketErrorListener (node:_http_client:504:5) {
  origin: 'provider',
  severity: 'fatal',
  details: { step: 'transfer', details: { details: [Object] } }
}
```

console.error(e.details.details)
```
{ details: { error: '' } }
````

And the default error message we used to see: `Transfer process failed.`
