Tier 1 of the SO->fp.job persistence audit. Three customer-reference
fields entered on sale.order's Plating tab were not flowing through
to fp.job (or SO lines), so the shop floor and printed paperwork
(traveller, BoL, cert) had to round-trip via sale_order_id every time.
Changes:
- fp.job: new x_fc_customer_job_number (Char, tracking), x_fc_po_number
(Char, tracking), x_fc_rush_order (Boolean, tracking). All three
populated by _fp_auto_create_job at SO confirm time.
- sale.order.line: x_fc_customer_job_number / x_fc_po_number added as
stored related fields off order_id so per-line list views show the
customer's references without navigating to the order header
(x_fc_rush_order was already on lines).
- fp.job form view: small Customer References group under the title
surfaces the three fields where the user expects them.
Verified end-to-end: SO -> SO line related fields -> fp.job direct
fields all carry the same value.
