Add verify_ack column to bulk_address_uploads (0219)

The "Verify classification" acknowledgement flag for ADR-0004 Step 1.
Gates Finalise whenever an upload has classifier columns, independent of
multi-entry, so it lives in its own column rather than on
multiEntryOrdering.

Plain additive column (boolean NOT NULL DEFAULT false), no data backfill,
so it applies cleanly with either `drizzle-kit migrate` or `push`. The
feature that reads/writes it lands separately on
feature/frontend_landlord_overrides.
