"""
Adds "dismissed" to DN_BATCH_NOTES.status.

Duplication happens per note, not per batch. The same stack of Vula
invoices was scanned three times in overlapping groupings (13, 16 and 14
pages, three different file hashes), so every one of those batches holds
a mix of promoted notes, duplicates of another batch, and invoices unique
to it. Dismissing a whole batch therefore either discards unique
invoices or zeroes a counter for notes already on the ledger.

"dismissed" lets a single duplicate note stand down, which is the only
safe granularity.

Idempotent.
