Update trading configuration to allow full fund utilization and adjust base size calculation in strategy

- Changed `max_position_usdt` to -1.0 to indicate that all available funds should be used if the value is less than or equal to zero.
- Modified the base size calculation in `LiveRegimeStrategy` to accommodate the new logic for `max_position_usdt`, ensuring it uses all available funds when applicable.
