Refine data staleness checks in MakerPointsEngine

- Updated the logic to only consider depth data for staleness checks, excluding account data from the criteria.
- Removed unnecessary account staleness checks from defense mode activation, streamlining the data validation process.
- Enhanced comments for clarity on the rationale behind the changes.
