Add debug logging to product retrieval for troubleshooting

Browse Source 
Added error_log statements to help diagnose why products aren't showing:
- Log selection criteria being used
- Log WP_Query arguments
- Log number of posts found by query
- Log each product being added (variable variations and simple)
- Log total products available at end

To enable: Set WP_DEBUG to true in wp-config.php
Then check debug.log or error.log for output
