Create an RFQ (taker)

Stages the trade — checks your funding and locks the quote — and answers **202** with `status: "settling"` plus `actions`: your own allocations to sign, one per instrument your legs touch (empty for a desk-signed house taker). Sign them all in one `POST /tx/execute`. One the desk could not queue at once follows as `sign.requested` (and in `GET /tx/pending`): until the outcome, sign what arrives for the trade. The desk adds its fee-receipt allocation and, once every allocation has landed, settles the trade in one transaction. The outcome arrives as `trade.settled` / `trade.failed` on the stream, or read it from `GET /trades` (settled) and `GET /rfq-history` (failed). A failed trade moves nothing; the quote is revoked and the RFQ stays open for another accept until its deadline. Unsigned allocations fail the trade about 11 minutes after the quote's `validUntil`; an action itself expires after 10, and until then the desk queues a fresh one in its place. An accept also drops any unsigned withdrawal of yours — or the maker's — in the trade's instruments, so it cannot spend the holdings the settlement needs: request it again after the outcome.
