"""drawing uploads stored with the package (CR-007 / D8)

The field wants the specific PDF attached, not a link to a Bluebeam session: a
general foreman opens the package and sees exactly the sheet relevant to their
scope, offline. The bytes live in this table - IN the same database as
everything else, settled Aug 18: splitting files out was rejected because a
backup that excludes the drawings is a backup you cannot restore from. The cost
of that decision is bounded by the D8 numbers, enforced in the API: 5MB a file,
PDFs and images only, 2GB per project with a warning at 80%.

Additive only: a new table, no change to any existing one, so nothing to
backfill and nothing to migrate.
