Auction craft breakdown

Paste an auction UUID for a craft cost breakdown. With HYPIXEL_API_KEY set in .env.local, the server fetches the Hypixel auction API and decodes item_bytes locally (gzip → NBT), or reads the Supabase AH snapshot (no key; full rescan at most about once per hour on breakdown submit, or anytime via GET /api/sync-active-auctions). Otherwise CoflNet listing + NBT is fallback. Kuudra-family armor uses a flat 500k per Basic piece + wiki essence path + enchants. Optional: paste raw item_bytes (gzip base64) to merge on top when something is still missing. Toggle Instant buy vs Instant sell for Hypixel bazaar material & enchant lines (default: buy). Rod line / hook / sinker use Cofl craft cost (recipe tree). BIN references from CoflNet.
