Add debug logging in RevenueSection for better price retrieval tracking

- Introduced console logs to track the number of better prices received for each product and the state of the betterPricesMap after updates.
- Enhanced the getBetterPrices method with logging to provide visibility into the prices being returned, improving traceability during price evaluations.
- These changes aim to facilitate debugging and provide clearer insights into the price handling process within the RevenueSection component.
