Update several work orders at once

Applies the same crew, status or scheduled date to several work orders in one request. Pass the IDs in work_order_ids and at least one of crew_id, status and scheduled_date at the top level of the body (not inside a work_order object).

• Each work order is saved separately, so the usual booking rules still apply. A work order that fails validation is left unchanged and listed in conflicts with the reason; the others are still updated.
• IDs the token's role cannot see are skipped.
• If none of the three fields is given, the request returns 422 and nothing changes.
• The token's role must have the Work production jobs permission, and the token needs the write scope.
