"""Per-package row for outbound multi-piece shipments.

Each fp.receiving has zero-or-more fp.outbound.package rows. When the
operator clicks Generate Outbound Label, one stock.package + one
carrier label is generated per row.

Single-box scenario: the form auto-fills one row when the receiving's
top-level weight/dim are set, so existing UX still works.
Multi-box scenario: operator adds more rows. Each row gets its own
tracking number + label PDF/ZPL stored back on the row after the API
call returns.
