Adds the Accounting → Incoming invoices frontend on top of the existing
/api/admin/expenses backend:
- accounting.service.ts: typed client (inbound upload/list/get/update/
categorize, expense list, re-bill, supplier-payment, categories).
- AccountingInboxPage: capture a supplier invoice via the device CAMERA
(<input accept="image/*" capture="environment">) or a PDF/image upload;
inbox list with status badges + parsed summary; a triage modal to confirm
fields and pick a disposition (re-bill / pass-through / company expense /
duplicate / declined). Re-bill uses the customer picker and mints an
editable scheduled invoice (chains categorize -> rebill).
- AccountingLayout: "Incoming invoices" sub-nav item + AccountingIndex that
redirects /admin/accounting to the first enabled sub-feature.
- App.tsx: /admin/accounting/inbox route (gated by incomingInvoices).
- i18n: accounting.inbox/disposition/markup + subnav.incomingInvoices +
common.saving (EN + DE, DE authored natively).
Camera capture needs no native app — the mobile web input drives the device
camera straight into the upload endpoint. OCR/QR auto-extraction is still a
backend follow-up (extractionService is a no-op), so fields are confirmed
manually in the triage modal for now.
Verified: npm run build green; en/de JSON valid.
