fix(checkout): create ERPNext Sales Order for compliance_batch orders

Batch orders (CB-XXXX, used by the trucking new-carrier flow and any multi-
service cart) never created an ERPNext Sales Order -- the SO-creation branch was
gated to order_type 'compliance' only. So those paid orders never reached
ERPNext for fulfillment/accounting (0 of all paid batch orders had an
erpnext_sales_order). Added a compliance_batch branch that creates ONE Sales
Order with a line item per service in the batch (+ government-fee + processing-
fee lines), then stamps the SO name on every batch row. Non-blocking like the
others. Also created the missing ERPNext Items the new slugs reference
(DOT-NEW-CARRIER-BUNDLE, LLC-FORMATION, CORP-FORMATION, NEW-CARRIER-BUNDLE which
was missing too, GOVERNMENT-FILING-FEE).
