feat: implement testnet and demo trading setup for XRPUSDT with 125x leverage

- Added support for demo trading on Binance Futures with a new configuration for 1-minute candles and 125x leverage.
- Updated various components including Config, Exchange, DataStream, UserDataStream, and Bot to handle demo and testnet flags.
- Enhanced the training pipeline to collect 1-minute data and adjusted the lookahead for model training.
- Updated environment variables in .env and .env.example to include demo settings.

This commit lays the groundwork for testing ML-based automated trading strategies in a controlled environment.
