feat: admin auto-solve button for quick level testing

- Add adminMode toggle in AdminPanel (green "Admin ON/OFF" button)
- Pass adminMode through GameApp → PuzzleView
- Show purple "🛠 Resolver" button in puzzle toolbar when admin is active
- Auto-solve gives 3 stars instantly and shows completion overlay
- Lets admin skip through all 96 levels for rapid testing
