Fix: Admin SPA Ana Sayfa dönüş problemi çözüldü

- Ana Sayfa butonu çalışmıyordu, sayfa yenileniyordu
- Engelleleyici genel condition kaldırıldı: if (page === '') → goto('/dashboard')
- Admin-specific Ana Sayfa case'i eklendi
- resetAdminStates() fonksiyonu ile tüm state'ler sıfırlanıyor
- Svelte reactivity için tick() eklendi
- Active buton durumları düzgün çalışıyor
- Single Page Application navigation artık sorunsuz
