search: Fix some inconsistencies between project and buffer search bars (#36103)

- project search query string now turns red when no results are found
matching buffer search behavior
- General code deduplication as well as more consistent layout between
the two bars, as some minor details have drifted apart
- Tab cycling in buffer search now ends up in editor focus when cycling
backwards, matching forward cycling
- Report parse errors in filter include and exclude editors

Release Notes:

- N/A
