The tool was using InvoiceExtractionSchema which forces every
lineItems.accountSuggestion to null via .transform() — the same guard
that prevents the AI extractor from hallucinating BAS accounts.
Agents supplying their own extraction should be able to pin a cost
account per line.
Adds AgentExtractionSchema (exported alongside ExtractionSchema)
where accountSuggestion accepts a validated BAS expense account
(class 4–7, /^[4-7]\d{3}$/) or null. set_inbox_extracted_data now
parses through this schema so the field survives the round-trip to
the DB and is available when gnubok_create_supplier_invoice_from_inbox
builds line items.
