Generalize vendor price display across all tooltip types

Replace the single GameTooltip hook with a comprehensive hooking system that displays vendor prices across 17+ tooltip methods, including loot, quests, bags, mail, auctions, trades, merchants, and crafting. This ensures players see vendor prices consistently regardless of where they view items.
