/**
 * SettingsView Behavior Tests
 *
 * Tests the settings view's store integration and API call patterns.
 * Given the complexity of UI interactions, these tests focus on:
 * 1. Store integration - how settings sync with app store
 * 2. API call patterns - validating expected API interactions
 * 3. LocalStorage persistence - credentials and preferences
