test(info): cover every Info API method body and InfoClient wrapper offline

[joeblau]

What & why

Tests only — no src/ changes. Brings src/api/info to 100% line coverage in the offline test run (HL_OFFLINE=1 bun test tests/), closing the gap where every method body (parse(params) + config.transport.request("info", …)) and every InfoClient wrapper was previously exercised only by the skipped-when-offline live tests.

How:

• tests/api/info/_mockInfoTransport.ts (existing mock): now also records the AbortSignal of each call, and is async so a throwing handler surfaces as a rejection the way a real transport's failures do.
• New tests/api/info/_offlineMethodTests.ts: a shared battery each method's test file runs — exact wire payload for every valid-params combo (defaults, optionals, nulls, picklists, orderStatus oid-as-number vs cloid), ValidationError with zero requests for invalid params, response/error/signal passthrough, and identical behavior through the InfoClient wrapper. Covers the params-or-AbortSignal overloads (allMids, meta, metaAndAssetCtxs, perpsAtOpenInterestCap) in both directions.
• The four paginated *All helpers whose InfoClient wrappers were uncovered (candleSnapshotAll, fundingHistoryAll, userNonFundingLedgerUpdatesAll, userTwapSliceFillsByTimeAll) get the same "is exposed on InfoClient with identical behavior" test as userFillsByTimeAll, including signal threading through the pagination loop.

One behavior worth noting: orderStatus with a small numeric-looking cloid (e.g. 0x000…01) sends oid as a number — the UnsignedInteger arm of the union matches first. The new tests pin that and use an out-of-safe-integer-range cloid (0xffff…) to cover the string arm.
