fix: use frontend_open_orders to return correct trigger prices

[0xaaditya]

Switched from open_orders to frontend_open_orders endpoint which returns full trigger metadata (triggerPx, triggerCondition, orderType) for TP/SL orders instead of stripping it out.

Code Review

This pull request updates the HyperliquidServices initialization to support API keys by allowing an explicit account_address and modifies get_open_orders to use the frontend_open_orders endpoint, providing more detailed order metadata. A critical logical flaw was identified in the new error handling logic where a failed wallet derivation is retried in the except block, which would cause an unhandled exception.

[gemini-code-assist]

The try-except block is logically flawed. If Account.from_key(private_key) fails on line 53, it will be called again on line 58 with the same input, which will inevitably raise the same exception and crash the initialization. This makes the except block redundant and misleading. Furthermore, if Account.from_key fails, self.wallet is never successfully assigned, which will cause a crash later when initializing the Exchange client on line 69. If the intention is to support API keys, note that they are still valid private keys that Account.from_key can parse; the only difference is that the derived address is for the API wallet, which is why providing an explicit account_address is necessary (and already handled by the logic on line 55).

Suggested change

	try:
	self.wallet = Account.from_key(private_key)
	# If account_address wasn't provided, try to use the wallet's address
	self.account_address = account_address or self.wallet.address
	except Exception as e:
	self.logger.warning(f"Could not derive wallet from private key (might be an API key): {e}")
	self.wallet = Account.from_key(private_key) # This might still work for signing if it's a valid hex string
	self.account_address = account_address
	try:
	self.wallet = Account.from_key(private_key)
	# If account_address wasn't provided, try to use the wallet's address
	self.account_address = account_address or self.wallet.address
	except Exception as e:
	self.logger.error(f"Could not derive wallet from private key: {e}")
	raise
