feat: Enhance useMarket composable with improved error handling and sample data loading

- Add detailed logging for market loading, configuration, stalls, and products to aid in debugging.
- Implement graceful error handling by creating default markets and stalls when data loading fails.
- Introduce a method to add sample products for testing when no products are found, improving development experience.
- Update market data fetching logic to ensure consistent handling of identifiers and event processing.
