Implement potion pool (小绿瓶) system

- Add potionPool property to Player (initial: 1000 HP)
- Add addPotionPool(), consumePotionPool(), hasPotionPool() methods
- Modify Battle.php to add healing drops directly to pool instead of inventory
- Update InventoryPanel.php useItem() to consume from pool
- Update InventoryPanel.php autoHeal() to use pool system
- Add pool display in inventory header and stats panel
- Healing items no longer take inventory space after drops
