feat(warehouses): prefill receive-to-warehouse from existing booking data

The receive form now arrives filled with everything the booking already knows,
instead of the operator re-typing it:

- container numbers come from the per-unit records (booking_container_units)
  entered at booking time, falling back to the line-level aggregate
- customs seal number prefilled from the units' seal numbers
- net weight prefilled from the booking's declared cargo weight (tonnes)
- driver signatory defaults to the arriving driver's name

Existing prefills (owner, TIN, phone, booking ref, cargo, packaging, unit
count, first-mile / customer truck + driver) unchanged; all fields stay
editable where they were editable before.
