fix: Ayarlar sayfasındaki switch'ler kapatılıp kaydedilince kalıcı olmuyordu

Radix Switch'in kendi gizli-input form entegrasyonu bu ortamda Server
Action'ın FormData'sına güvenilir şekilde ulaşmıyordu — switch'i "off"
yapıp Kaydet'e basınca eski değer kalıcı oluyordu (STT hep otomatik
çalışmaya devam ediyordu). Artık her switch kendi değerini doğrudan
kontrol eden bir hidden input'la (SettingSwitch) submit ediliyor,
Radix'in iç mekanizmasına bağımlı değil.
