Updates December 29

PGrid

• Added the ability to manually fail items. This keeps an item’s price history, but prevents further scraping (for cases where there was bad classification, or if the item URL changed products entirely).
• eBay scraper showed high error rates; updated a specific JSON parsing step to be more stable
• Work in progress on RAM classification and specs search
  • Got brand classification + specs search working OK
  • partial model stage completion
