feat: segment süresi varsayılanını 15 dk -> 5 dk düşür + dashboard'u kart-grid'e çevir

Global SEGMENT_TIME_SEC varsayılanı 900->300 (docker-compose, .env.example,
env.ts, signal_detection.py fallback'i) — kanal bazlı override zaten
panelden ayarlanabiliyordu, bu sadece varsayılanı değiştiriyor.

Dashboard'daki kanal listesi tablo yerine kart-grid: her kanal kendi
kartında, durum rozetleri üstte belirgin, aksiyonlar altta — önceki
tablo düzeni (özellikle aksiyon sütunundaki sıkışık butonlar) okunması
zor bulunuyordu.
