Refactor MakerPoints configuration and depth handling

- Renamed `band0To10MinDepth` to `filterMinDepth` in `config.ts` for clarity.
- Updated `MakerPointsEngine` to utilize the new `filterMinDepth` for depth checks across all bands.
- Introduced a method to track depth status changes, enhancing order placement logic based on market depth.
- Improved logging for depth-related order skips to provide clearer insights into trading decisions.
