- src/inventory/vendor.py: Log screenshots when NotEnoughGold detected
  during gambling, purchasing, and repairing
- src/ui_manager.py: Update NotEnoughGold to use new MISSING_GOLD template
  from assets/npc/missing_gold/ (full dialog match instead of color-based)
- assets/npc/missing_gold/missing_gold.png: New template for the popup
