+  2. GET /invoices/import-batch/:id → état courant du batch (le SPA poll pendant la review).

+     - POST .../drafts/:draftId/skip → marque le draft `skipped`
+  4. DELETE /invoices/import-batch/:id → annule le batch entier (cascade sur les drafts ; les invoices déjà créées restent).

+  ⚠️ V1 : OCR_PROVIDER=mock. Mistral arrive en commit séparé (cf. ADR-020).
