`WhaleApiResponse` should include a "meta" field that include defid node stats.

#### What would you like to be added:

https://github.com/JellyfishSDK/jellyfish/blob/7e88ff530a4f97216086c6e09ec23654c7778033/packages/whale-api-client/src/whale.api.response.ts#L4-L8

Should include:

```json
{
"data":{},
"meta": {
"blockchain": {
"hash": "923fe2d3f5920163d2401095de5647ce25ee3463863fad04e76eec48719fb8a3",
"height": 1398516,
"medianTime": 1637921787,
"time": 1637921973
}
}
}
```

#### Why is this needed:

Including blockchain information to `WhaleApiResponse` will make it easier for the client to determine the `ApiResponse` is reliable and up to date before they perform their subsequent actions.

Start with packages/whale-api-client/src/whale.api.response.ts at the linked lines and inspect how WhaleApiResponse currently models API results. Compare that type with the issue's example, then trace its response usage to confirm the expected shape. Done means the response type represents data alongside blockchain hash, height, medianTime, and time metadata.
