Fixes#2257
This is a follow-up to the public collections work, which adds pages to
the database for uploads. All crawls and uploads now have a `pageCount`
field which is populated when the item is successfully added. A new
migration is also added to populate the field for existing archived
items that don't have it set yet.
OrgMetrics have also been modified to include `crawlPageCount` and
`uploadPageCount`, and to include the total of both in `pageCount`, and
all three included in the frontend org dashboard.
The frontend has been updated to use `pageCount` rather than
`stats.done` wherever appropriate, meaning that in archived item lists
and details we now have a consistent page count for both crawls and
uploads.
### New functionality
- Deploy this branch
- Create new crawls and uploads and verify that page count appears
correctly throughout the frontend for all new crawls and uploads
### Migration
- Deploy from latest main
- Create some crawls and uploads
- Change to this branch and re-deploy
- Verify migration ran without errors in backend logs
- Verify that page count has been populated successfully by checking
archived items lists, crawl and upload detail pages, and dashboard to
ensure there are no longer any missing page counts.
