/**
 * KIN-120: Тесты SettingsView — навигатор по настройкам проектов
 *
 * После рефакторинга SettingsView стал навигатором:
 * показывает список проектов и ссылки на /project/{id}?tab=settings.
 * Детальные настройки каждого проекта переехали в ProjectView → вкладка Settings.
 *
 * Проверяет:
 * 1. Загрузка и отображение списка проектов
 * 2. Имя и id проекта видны
 * 3. Ссылки ведут на /project/{id}?tab=settings
 * 4. execution_mode отображается если задан
