Dispatch performance:
- Replace sequential batch fetches (batches of 15, one after another)
with full parallel Promise.all — all doc fetches fire simultaneously
- With 20 jobs: was ~3 sequential round-trips, now ~2 (1 list + 1 parallel)
Order traceability:
- Add sales_order (Link) and order_source (Select) fields to Dispatch Job
- checkout.js sets order_source='Online' + sales_order link on job creation
- acceptance.js sets order_source='Quotation' on quotation-sourced jobs
- Store maps new fields: salesOrder, orderSource
