⚒️ Extreme Upgrade System

🖥️ UI Improvements

 - The Extreme Upgrade window now displays the total Core Power of registered cores.  
 - Previously it showed only the core level.  
 - Core Power is now also visible directly in the Extreme Core tooltip.  
This gives you clear visibility of the real power you are stacking, not just the level number.```  
### 🎯 Success Outcome Rate Adjustments  

We adjusted the balance between Item Broken and Extreme Upgrade Deleted results on high levels.
Lv. 7 → 8

• Item Broken: 80%
• E.U. Deleted: 20%
  Lv. 8 → 9
• Item Broken: 70% (Old 60%)
• E.U. Deleted: 30% (Old 40%)
  Lv. 9 → 10
• Item Broken: 60% (Old 40%)
• E.U. Deleted: 40% (Old 60%)
  Higher levels now shift more weight toward item break instead of full Extreme Upgrade deletion compared to previous values.```

♻️ Extractable Extreme Levels 12–15

 - Added extractable variants for EX Lv. 12 to Lv. 15  
 - Available via Hirogley NPCs in:  
  - Bloody Ice (BI)  
  - Port Lux (PL)  

💎 Extreme Core Pocket (Premium)

Now supports Extreme Cores Lv. 6 to Lv. 15  
 - Previously capped at Lv. 12.  
Level 6 core drop rate reduced  
The reduced rate was redistributed equally to:  
 - Lv. 13  
 - Lv. 14  
 - Lv. 15  
High-end progression is now more accessible, but still high risk and high value.```
