Ended auctions database

Every row the EC2 poller captured from Hypixel auctions_ended (deduped, ~7 day retention). Click a row for full decoded NBT (item_bytes → enchants, ExtraAttributes, etc.). Backfill on EC2: npm run auctions-ended:decode-nbt. Source: data/auctions-ended-database.json.

Data accumulates on the API host via the scanner worker every ~15s. Use Refresh for latest counts.
