New Feature: Inventory-Safe Purchase Handling
MythicAuctionHouse now prevents item loss when a player's inventory is full during a purchase.

If a player buys an item and their inventory does not have enough space:

✔ The purchased item is automatically moved to /ah storage
✔ It is marked as a purchase delivery item
✔ It cannot be relisted
✔ The player receives a clear message:

"Your inventory is full. Claim your purchase in /ah storage."

No more:
❌ Items dropping on the ground
❌ Risk of despawning
❌ Players losing purchases
❌ Exploits through forced overflow
