Enhance MakerPoints functionality and configuration

- Updated `filterMinDepth` in `config.ts` from 1 to 50 to improve depth filtering logic.
- Added new translation entries for band depth display in `i18n/index.ts`.
- Introduced `bandDepths` to `MakerPointsSnapshot` in `maker-points-engine.ts` to track depth across different bands.
- Enhanced `BinanceDepthTracker` to support dynamic depth levels and speed settings.
- Updated `MakerPointsApp` to display band depth information, improving user interface clarity.
