VAT supplier-country reclaim default: - Migration 134 adds inbound_documents.supplier_country. - categorizeInbound auto-derives tax_treatment via resolveTaxTreatment: explicit treatment wins; else country in the reclaim list → domestic, outside it → foreign_vat_non_reclaimable, unknown → domestic. Consumes the previously-stored-but-unused accounting_vat_reclaim_countries. - Triage modal gains a Supplier country dropdown (saved via updateInbound). +5 unit tests for resolveTaxTreatment. Configurable default output VAT code for new invoices: - New accounting_default_output_vat_code setting (PUT wired; getSettings/type). - Settings → Accounting dropdown to pick it. - Invoice + quote editors seed their VAT picker (rate + code) from it on a blank new document — skipping edits/conversions, never clobbering a touched value. New docs no longer silently start at 0%. i18n en + de.
