Description

Related to https://github.com/webrecorder/browsertrix/issues/2906

The current /crawls/tagCounts endpoint excludes failed and cancelled crawls (which matches its usage in the Archived Items tab), but for the new Crawl Runs view in the Crawling tab we'll want to include those.

We should modify this endpoint to have a flag to include all crawls regardless of status.
