/**
 * Step 1: Export a job to Reynolds & Reynolds as a *new* Repair Order.
 *
 * This is the "create" phase only:
 *  - We always call client.createRepairOrder(payload, opts)
 *  - Any follow-up / finalUpdate is handled by finalizeRRRepairOrder
 *
 * When in RR mode (bodyshop.rr_dealerid truthy), we also:
 *  - Extract responsibility center config (for logging / debugging)
 *  - Run CdkCalculateAllocations to produce the allocations array
 *    (with profitCenter/costCenter + rr_gogcode / rr_item_type / rr_cust_txbl_flag)
 *  - Derive a default RR OpCode + TaxCode (if configured)
 *  - Pass bodyshop, allocations, opCode, taxCode into buildRRRepairOrderPayload
 *    so it can create the payload fields used by reynolds-rome-client:
 *    - header fields (CustNo, AdvNo, DeptType, Vin, etc.)
 *    - RO.rolabor (ops[])
 *    - RO.rogg (ops[])
 *    - RO.tax (TaxCodeInfo)
 *
 * @param args
 * @returns {Promise<{success, data: *, roStatus: *, statusBlocks, customerNo: string, svId: string|null, roNo: *}>}
