Remove TimestampMixin (created_at/updated_at) from Purchase, PurchaseItem, PriceHistory, Coupon, and ShrinkflationEvent models since their PostgreSQL tables do not have those columns. This was causing 500 errors on /api/v1/purchases and /api/v1/purchases/stats. Co-Authored-By: Paperclip <noreply@paperclip.ing>
