feat(s5-iqc): complete route B shadow inventory posting (态② FINAL PASS WITH LIMITATION)

- C1 IqcResultMapping (MRB 5-branch routing) + C2 IqcReceiptOrchestrator
- C5 InventoryTransactionService (9 guards + balance calculator + FOR UPDATE UoW)
- C6 PurchaseReceiptWriteback + C7 InventoryMobileTask (DOP-owned ado_* shadow)
- L1 IqcInventoryEventConsumer: idempotency 4-state, stale recovery, completion crash recovery, freshness fail-closed, domain resolver
- L0 MdpIqcReceiptStateLoader + IqcReceiptStateMdpSyncService (态① read-only staging)
- RctNbr via NumberRuleService in outer transaction; DOP-owned inventory ledger schema
- tests: unit + integration harness (AIDOP_IT gated) + L4 shadow reconciliation
- verified on aidopdev: UNIQUE/1062/FOR UPDATE/concurrency/rollback/crash recovery/production shadow E2E/L4 reconciliation

Shadow status: FINAL PASS WITH LIMITATION. No authoritative cutover. server 1.0.302.
