Result of browser.url

### Contribution

- [ ] I'd be willing to implement this feature ([contributing guide](https://github.com/gemini-testing/testplane/blob/master/CONTRIBUTING.md))

### Describe the user story

Есть необходимость написать тест с проверкой заголовков ответа и цепочки редиректов.

### Describe the solution you'd like

Можете ли добавить возможность получения результатов browser.url как в чистом webdriver - https://webdriver.io/docs/api/browser/url/#examples ?

```javascript
// navigate to a new URL
const request = await browser.url('https://webdriver.io');
// log url
console.log(request.url); // outputs: "https://webdriver.io"
console.log(request.response?.status); // outputs: 200
console.log(request.response?.headers); // outputs: { 'content-type': 'text/html; charset=UTF-8' }
```

### Describe the drawbacks of your solution

_No response_

### Describe alternatives you've considered

_No response_

Start with the browser.url entry point and compare its current behavior with the WebdriverIO browser.url examples linked in the issue. Trace how navigation results are returned, then verify that the result exposes the final URL, response status, headers, and redirect-chain information described in the request.
