fix: poll hatasına zaman damgası ekle + STT'yi panelden kapatılabilir yap

- lastPollErrors artık {message, at} tutuyor — panelde hangi hatanın ne
  zaman oluştuğu görünmüyordu, eski/güncel ayrımı yapılamıyordu.
- "This live event will begin in N minutes" gibi zararsız mesajlar da
  hata rozetine düşüyordu, "is not currently live" ile aynı gruba alındı.
- Yeni stt_enabled ayarı (Ayarlar sayfası): kapatılınca stt_scoring.py
  OpenAI Whisper çağrısı yapmadan adayı PENDING_STT'de bırakıp çıkıyor —
  konuşmasız/ambiyans yayınlarda (bkz. NASA testi) boşa API maliyeti
  önleniyor.
