Implements the split decided in review: Incoming invoices (external) - the inbound_documents row IS the payable: - categorizeInbound now UPDATES the document (disposition + tax_treatment + booking event_id (null=company) + category), no derived expense row, so a supplier invoice appears only in the incoming-invoices surface. - rebillInbound mints the client invoice from the document (base = invoice total + markup) and links it on the doc. - markInboundSupplierPayment records supplier payment ON the incoming invoice (mark-paid lives here now). Expenses (internal) - own costs only: - createExpense: kind = amount|mileage|per_diem; amount = quantity x rate (rate from accounting settings, per-entry override; snapshotted); optional proof file; booked to an event or the company; require-proof enforced from settings. No supplier payment, always own-cost. - listExpenses returns internal rows only (inbound_document_id IS NULL). Routes: per-flag gating (incomingInvoices vs expenses; categories on the accounting master); supplier-payment + re-bill moved under /inbound/:id/*; POST/PATCH expenses accept a multipart proof upload; GET /:id/proof streams it (PDF download-only, image inline). getAccountingSettings reads app_settings. Verified: node -c, require-graph, 12 unit tests (markup + expense amount/build). Frontend rework (service + the two UIs + settings tab + category i18n) follows.
