Add Binance depth monitoring configuration to MakerPoints

- Introduced new environment variables `MAKER_POINTS_BINANCE_DEPTH_WINDOW_BPS` and `MAKER_POINTS_BINANCE_DEPTH_IMBALANCE_RATIO` to configure Binance depth monitoring.
- Updated `MakerPointsConfig` interface and implementation to include these new parameters.
- Enhanced translations to reflect dynamic depth window information in the UI.
- Added tests to validate the new configuration options and their integration into the MakerPoints engine.
