add: scripts for invoice-order matching and SKU discovery

Analysis scripts to match GoMag orders with Oracle invoices by
date/client/total, then compare line items by price to discover
SKU → id_articol mappings. Generates SQL for nom_articole codmat
updates and CSV for ARTICOLE_TERTI repackaging/set mappings.
