fix: move account trades to CLOB unified endpoint

[cesarenaldi]

Summary

• move listAccountTrades() from legacy /data/trades to unified /v1/account/trades
• map SDK request fields to unified query params: market -> market_id, tokenId -> token_id, and SDK cursors to unified offset
• update account trade bindings for unified response fields, including nested maker-order token_id and has_more pagination
• add focused binding coverage for the unified account trade response shape
• add a patch changeset for @polymarket/client and @polymarket/bindings

Fixes #76
Linear: DEV-175

Verification

• pnpm test:bindings
• pnpm lint
• pnpm typecheck
• pnpm --filter @polymarket/types build && pnpm --filter @polymarket/bindings build && pnpm test:client && pnpm typecheck

Note

Medium Risk
Switches a core account data path and pagination semantics; wrong offset/hasMore handling could drop or duplicate trades for integrators.

Overview
Account trade listing now calls the unified CLOB route /v1/account/trades instead of legacy /data/trades. SDK filters map to unified query params (market → market_id, tokenId → token_id), and pagination uses offset under the hood (default page size 50) while still exposing the existing cursor-based paginate API.

Bindings in @polymarket/bindings were aligned with the unified payload: trades and nested maker orders use token_id / market_id, the trades page uses has_more (not next_cursor), and a few fields are optional (fee_rate_bps, transaction_hash). Normalized client fields (market, tokenId, timestamps, etc.) are unchanged after Zod transforms. A focused ClobTradeSchema test documents the unified response shape.

Patch changesets cover @polymarket/client and @polymarket/bindings.
