Per-player instant shop for Sigma Orders & Auction

What it does
QuickBuy gives each player their own personal shop of up to 54 configurable slots, each bound to an item from the live Sigma Orders auction house. Click a slot, QuickBuy instantly finds and purchases the cheapest active listing for that item, no browsing required. The slot lore refreshes after every click so what you see is always live.
Why this over other shop plugins?

Why this over other shop plugins?
- Prices are live, not static - every purchase pulls from the real auction market at the moment of the click, not a fixed price list.
- If the targeted listing is bought by someone else a split-second before your click, QuickBuy silently falls through to the next cheapest - no errors, no failed clicks.
- Set a max price cap per slot, or leave it empty for No Limit to always grab the absolute cheapest listing.
- Require minimum enchantment levels on purchased items - only listings that meet the requirement qualify.
- Permission-based slot allotments let you give VIP players more slots. Conflict resolution always picks the highest limit - never first-match.
