"""
Adds dn_batches.open_pages.

A page belonging to no document used to fail the pages_accounted check,
which put the whole batch in needs_attention. Batch 5qzcv6tvgb6cqks
promoted 3 of 3 notes correctly and still read as a failure because its
fourth page was a tax invoice cover sheet.

Open pages are questions, not failures: they are listed, counted, and
dismissable, while the requirement that every DETECTED note promotes is
unchanged.

Idempotent.
