Initial commit: sap-legacy-webhook-emulator

Reconstruye el Webhook Messenger nativo de SAP B1 (FP2605) para
clientes que aun no estan en esa version: captura eventos via
SBO_SP_PostTransactionNotice, provisiona UserTables OEVC/EVC1/OEVN/EVN1
y despacha CloudEvents al mismo endpoint que el messenger real.
