fix(freight): filter container returns by returned-by truck type

Top Returned Containers table ignored the EDR/Customer tab because
the backend never persisted which truck type performed the return.
Added returned_by column + DTO/entity field, wired create payload to
send it, and filtered the table by the active tab.
