fix(web): preserve regex and case sensitivity params in search load-more (#972)

* fix(web): preserve regex and case sensitivity params in search load-more

When clicking the "load more results" button in /search, the isRegexEnabled and isCaseSensitivityEnabled query parameters were being dropped. This fix includes these parameters in the URL built by onLoadMoreResults, matching the behavior of the initial search submission.
