improve: [codex] Set Binance recvWindow by endpoint

[nicholaspai]

What changed

• removed the custom Binance server-time synchronizer from getBinanceApiClient()
• introduced a simple endpoint-level recvWindow policy in src/utils/BinanceUtils.ts
• route signed read-only calls through shared helpers with recvWindow = 60000
• route signed write-state calls through shared helpers with recvWindow = 5000
• updated Binance call sites in the rebalancer, finalizer, and bridge adapters to use those helpers
• added focused tests that pin the read/write recvWindow behavior

Why

The original goal is narrow: avoid Binance -1021 INVALID_TIMESTAMP / recvWindow errors without adding unnecessary complexity.

After reviewing the signed Binance calls in this repo, the cleanest policy is:

• signed writes should stay tight, because we do not want delayed accepted requests to submit state-changing actions much later than intended
• signed reads can tolerate a much larger validity window, because a delayed accepted request still returns current server data at processing time

That means we do not need a custom client-side time synchronizer here.

Policy

• write-state endpoints: recvWindow = 5000
  • market order()
  • withdraw()
• signed read/setup endpoints: recvWindow = 60000
  • tradeFee()
  • depositAddress()
  • allOrders()
  • accountCoins() / capital/config/getall
  • depositHistory()
  • withdrawHistory()
  • withdraw quota reads

Notes

This is still not a substitute for keeping the host clock reasonably synced. A larger recvWindow helps with stale timestamps, but it does not fix the case where the local clock is ahead of Binance.

Validation

• yarn test test/BinanceUtils.ts
• yarn eslint src/utils/BinanceUtils.ts src/rebalancer/adapters/binance.ts src/adapter/bridges/BinanceCEXBridge.ts src/adapter/bridges/BinanceCEXNativeBridge.ts src/adapter/l2Bridges/BinanceCEXBridge.ts src/adapter/l2Bridges/BinanceCEXNativeBridge.ts src/finalizer/utils/binance.ts test/BinanceUtils.ts
• yarn build
