Add Debug trait implementations for all structs and enums

- Added #[derive(Debug)] to ClientModifyRequest
- Added #[derive(Debug)] to ClientLimit, ClientTrigger, MarketOrderParams, MarketCloseParams, ClientOrder, ClientOrderRequest
- Added #[derive(Debug)] to ClientCancelRequest and ClientCancelRequestCloid
- Added #[derive(Debug)] to ExchangeClient
- Added #[derive(Debug)] to HttpClient

Fixes hyperliquid-dex#52
