Response Search Improvements

## :warning: Is your feature request related to a problem? Please describe.

One related problem is that when you perform a search in the response tab, any highlighted matches will be unhighlighted as you scroll through the body of the response. Furthermore, the act of searching does not auto scroll to the first occurrence of the search result as I would expect.

## :dart: Describe the solution you'd like

I propose the following:
- As you type a search query, the body should auto scroll to the first occurrence of the search term
- Proper highlighting be maintained for search results as you scroll through the body of the response
- Additional search controls be introduced to allow for navigating between next and previous search results with additional meta data displaying the current visited search result index and the total count of search results shown.
