feat: icon extraction from .exe files

Browse Source 
- electron/main.ts: extractExeIcon() via app.getFileIcon(), saves PNG to
  userData/icons/{md5}.png; IPC icon:extract; scanner:import now auto-extracts
- electron/preload.ts: expose extractIcon()
- AdminPanel: Scan button next to image field — extracts icon from current exe
  (shows animated pulse while loading, error if no exe selected or extraction fails)
- GameCard: isExtractedIcon() detects icons/ path; renders centered 64x64 icon
  on gradient background instead of stretched cover
