/**
 * GET /api/accounting/incoming-invoices/next-review?after=<inboxId>

 * The documents waiting for review — for the review screen's ‹ › browsing (`ids`) and its
 * "complete & next" button (`nextId`).
 * Follows the inbox list order (newest first): the first open document AFTER the given one,
 * wrapping around to the top. Returns only ids (the list route carries the PDF thumbnails).
