feat(BT12-Dev): MeleeArea 실전 발사 연결 + FX AutoDestroy unscaledTime (PD 지시 2026-05-13)

작업 1 — 스킬 배워도 이펙트 X fix:
- SkillFireEvent.Execute — MeleeArea case 추가 (CardId 분기·TestSkillFireOn1to5 동일 패턴)
  - A04 → LightningStrikeSpawner
  - A_Laser → LaserSpawner
  - 기타 → MeleeAreaSpawner

작업 2 — 맵 이동 중 이펙트 잔상 재발 fix:
- 원인: Object.Destroy(fxGo, t) 영역 second timer 영역 Time.timeScale 영향·timeScale=0 (LevelUp) 영역 호출 정지
- 신규: FxAutoDestroyUnscaled MonoBehaviour — Update 영역 unscaledTime lifetime check 자가 Destroy
- ProjectileSpawner·Projectile·MeleeAreaSpawner·LaserSpawner·LightningStrikeSpawner 모두 영역 Object.Destroy(fx, t) → FxAutoDestroyUnscaled.Attach
- LightningStrikeSpawner.DelayedExtraHitFx — WaitForSeconds → WaitForSecondsRealtime (timeScale=0 영역 정합)

본 PM 자성 #12 — feedback_new_code_existing_system_dependency_unmeasured 위반. Object.Destroy(go, t) 영역 timeScale 영향 사전 측정 누락 (Unity 표준 API).
