Исправление бесконечного рендер-цикла SearchView и поиск по публичному ключу

- SearchViewModel: заменён @Observable на ObservableObject + @Published
  (устранён infinite body loop SearchView → 99% CPU фриз после логина)
- SearchView: @State → @StateObject, RecentSection: @ObservedObject
- Добавлен клиентский поиск по публичному ключу (сервер ищет только по нику)
- ChatDetailView: убран @State на DialogRepository singleton
- ChatListView: замена closure на @Binding, убран DispatchQueue.main.async
- MainTabView: убран пустой onChange, замена closure на @Binding
- SettingsViewModel: конвертирован в ObservableObject
- Добавлены debug-принты для отладки рендер-циклов
