feat: add option to exclude current month data
Enhanced `get_transparency_data` to support an `allow_current` flag, preventing the inclusion of data from the current month. This ensures historical data analysis remains consistent when current month data might be incomplete. Updated calls to the function to pass appropriate parameters.
