bomberman: sunete (sfx), raza initiala 1, powerup-uri raza/bombe

Feedback user: nu se aud sunete, raza prea mare, lipsesc powerup-urile.

- sfx(type) WebAudio local in arcade: bomb/explosion/enemy/powerup/death;
  beep(ok) din libJS ramane pentru raspuns corect/gresit.
- raza fixa EXPLOSION_RANGE=3 -> bombRange variabil de la BASE_RANGE=1
  (Bomberman clasic); maxBombs de la BASE_BOMBS=1.
- powerup-uri: la spargerea cutiei, sansa 0.32 sa cada flacara (raza+1)
  sau bomba (bombe+1); ridicate mergand pe ele; HUD arata bombe/raza.
- fix: powerup-ul cadea pe celula cutiei si checkExplosionHits il stergea
  instant -> colectez brokenBoxes, drop dupa checkExplosionHits.

Hooks __game: powerups/bombRange/maxBombs/dropPowerupAt. Smoke 27/27.
