fix(market): pin auctionInfo to FIFA 17's twelve atoms, add the real auction clock

Browse Source 
Corrects the record against the CLIENT BINARY rather than library hearsay, using
the project's own reverse-engineering record
(fifa17-recon/docs/plan-2026-08-06-transfer-market.md, read out of the on-disk PE).

REVERTED (refuted): `tradeOwner`, `sellerId`, `offers`. FIFA 17's auctionInfo
deserializer (0x18013e410) reads exactly TWELVE atoms -- bidState, buyNowPrice,
currentBid, expires, itemData, sellerEstablished, sellerName, startingBid,
coinsProcessed, tradeId, tradeState, watched -- and value-SKIPs everything else at
0x180135ff0. Those three fields were added last commit on the strength of
contemporaneous FIFA 17 libraries; the PE says the client never reads them, so they
were inert and could not have been the Actions-panel gate. A preservation emulator
must not emit fields the client does not consume. New test pins the exact set.

ADDED: the auction clock. `expires` is SECONDS REMAINING (never an epoch) and the
client renders a LIVE COUNTDOWN it expects to reach 0. We hardcoded 3600, so no
auction ever aged or ran out. Now `duration` is taken from the ISStart body
(additive `duration_secs` column, defaulting to 3600) and `expires` is derived from
created_at + duration - now, clamped at 0. An active listing whose clock has run
out projects as `expired`/`none`/`expires: 0` -- FIFA 17's relistable state, per the
lifecycle table (active=1 inactive=2 expired=3 closed=4; none=0 outbid=1 highest=2
buyNow=3, both closed vocabularies). Pure projection: no row is mutated, so no
sweeper and no race with the economy.

ADDED: `duplicateItemIdList: []` on GetTradePile, which shares one deserializer
(0x18013e7f0) with ISSearch/ISWatchList over four members and we were omitting one.

CONFIRMED by the same source, so kept: `GET ut/{ns}/trade/status?tradeIds=a,b,c` is
real (ISVIEWTRADE) and my handler matches it exactly, including the comma list.
`ISREMOVETRADE` is `DELETE ut/delete/{ns}/trade/{tradeId}` -- our ORIGINAL spelling
was right. The plain-DELETE arm stays because the same source advises dispatching
on path and being method-agnostic (HTTP verbs are not statically recoverable).

Differential returns to strict key-set parity, with a comment recording WHY parity
is not sufficient: a field absent from both sides is invisible to it.

333 tests pass, 0 failed, clippy clean. Verified live: the twelve-atom record, the
four-member envelope, and the listing correctly reading expires=0 / expired after
aging past its hour.
