Paging - trdrs Engine API

Order history and closed round-trips are keyset-paged, newest first. The loop is three lines of logic:

Call the route. Read nextCursor from the response.
If nextCursor is a string, pass it back verbatim on the next call.
If nextCursor is null, you have the last page.

let cursor: string | null = null
do {
  const page = await get(`/api/account/orders/history${cursor ? `?cursor=${cursor}` : ''}`)
  rows.push(...page.orders)
  cursor = page.nextCursor
} while (cursor)

Cursors are opaque. Do not parse, build, or store them across sessions. A malformed cursor is rejected with 400 rather than silently resetting you to page one, so a bug in your pager shows up as an error instead of duplicate data. Keyset paging means new rows arriving mid-scroll never shift your pages. You will not see the same order twice because something filled while you were paging.
