Title: Binance Futures Testnet private API calls routed to Live Spot API (Invalid Api-Key ID)

Body:

Hello CCXT team,

I am experiencing an issue when trying to connect to the Binance Futures Testnet using the CCXT library.

Problem Description: My goal is to trade on the Binance Futures Testnet.

Public API calls work correctly: I can successfully fetch the server time (exchange.fetch_time()) from the Futures Testnet API. The verbose output confirms that this request correctly goes to https://fapi.binance.com/fapi/v1/time.

Private API calls fail and are misrouted: When I try to make private API calls, such as exchange.fetch_balance(params={'type': 'future'}) or exchange.fetch_positions(['BTCUSDT']), the request is incorrectly sent to the Binance Live Spot API domain (https://api.binance.com/sapi/v1/capital/config/getall) instead of the Futures Testnet API (https://testnet.binancefuture.com/fapi/v1).

Error received: The request to the incorrect endpoint then returns an HTTP 400 Bad Request with the error message: {"code":-2008,"msg":"Invalid Api-Key ID."}.

What I have confirmed:

API Keys: My API keys (API Key and Secret Key) are correctly generated from and belong to the Binance Futures Testnet (https://testnet.binancefuture.com/). I have double-checked this on the official Futures Testnet website.

CCXT Version: I am using the latest stable version of CCXT, 4.4.95.

Code Configuration: My code explicitly sets defaultType: 'future', setSandboxMode: True, and attempts to override the urls with https://testnet.binancefuture.com/fapi/v1 for fapi, fapiPublic, fapiPrivate, and general api, public, private keys, to ensure proper routing.

Expected Behavior: Private API calls for the Futures Testnet should be routed to https://testnet.binancefuture.com/fapi/v1/... and authenticate successfully with the provided Futures Testnet API keys.

Steps to Reproduce:

Obtain API keys from https://testnet.binancefuture.com/.

Set up a .env file with BINANCE_TESTNET_API_KEY and BINANCE_TESTNET_SECRET_KEY.

Run the provided Python code.
