Moved the search bar to the right of the body so that it doesn't hide the string in initial row

Moved the search bar to the right of the request/response body by 50% so that the search bar doesn't hide with the text when the search bar is opened.

Closes #7752

Response body

I seem to understand that this is the search bar for the JSON request body. It seems counterintuitive to show it all the way to the right in the response section, as the user may mistake it for a response filter.

Ideally, when we load the search bar, the request body should go down instead of overlying the search bar on top of the body. This would allow us to fix the issue, while still retaining the search bar in the right place.
