[IMP] stock_picking_batch_collect: collected checks on transfers, ordered quantity, delivery slips report

- The collected checks also apply to transfers outside a batch, opt-in per
  operation type ("Require Collected Lines"), with the batch restrictions of
  the settings. A per-product toggle in the transfer's Operations tab collects
  all its lines.
- Read-only ordered quantity from the sale line on every batch and transfer
  view, since the weighed demand overwrites it. Adds a dependency on
  sale_stock; a migration fills it in the summary of open batches.
- "Delivery Slips" report on the batch: all its delivery slips in one PDF.
