Subject: [PATCH] refactor: Enhance stall and product loading logic in
 useMarket composable

- Update the loadStalls and loadProducts functions to filter events based on the active market's merchants instead of fetching from all authors.
- Improve logging to provide clearer insights into the loading process and the merchants involved.
- Add checks to handle cases where no active market or merchants are found, preventing unnecessary API calls.
