refactor(ui): Remove obsolete code

With new API endpoints, item count functions are no longer needed in the
UI code, so remove them. Also, as `VulnerabilityRating` is finally
exposed from back-end, no need to keep a copy of it in the UI code
either.

Further cleanup will be possible, once the
`...runs/${runId}/vulnerabilities` endpoint also returns the overall
vulnerability rating directly instead of calculating it in front-end.
