feat: Show crawl page progress

[SuaYoo]

Resolves #3524

Changes

• Displays progress of page crawled so far in crawl runs list
• Displays number of found pages in crawl runs list, removing "Run by" column to recover more space
• Sort superadmin active crawls by "Pages Crawled"
• Replaces irrelevant QA column of latest crawl stats with "Pages Found"
• Makes latest crawl in workflow crawl history clickable, removing redundant "Watch crawl" notice
• Documents crawl run history in user guide

Manual testing

1. Log in as crawler
2. Go to "Crawling"
3. Start a workflow crawl
4. Go to "Crawl Runs"
5. Wait for crawl to begin running. Verify page crawl progress is displayed
6. Go to running workflow
7. Go to "Crawls". Verify page crawl progress is displayed
8. Click running crawl. Verify navigation to "Latest Crawl" tab

Gave this a test locally, and working well! Looks good too. I think this is a nice win for usability.

Do we keep track of how many pages we found after a crawl finishes? It would be interesting to be able to show this for completed crawls too, or at least for stopped crawls where it was manually halted before it got to everything.
