feat(hyperliquid): Add Unified Account support for Spot as Perp collateral (#1387)

Browse Source 
This PR adds support for Hyperliquid's Unified Account mode where Spot USDC
balance can be used as collateral for Perpetual trading.

Changes:
- Add HyperliquidUnifiedAcct field to Exchange config (default: true)
- Update HyperliquidTrader to support unified account mode
- When enabled, Spot USDC balance is added to available trading balance
- Update API request/response structs for unified account toggle
- Update trader config propagation from exchange config

This aligns with Hyperliquid's roadmap to make Unified Account the default.
