/**
 * Settings Error Detection UI Test
 *
 * Tests settings page for error messages that appear when changing values.
 * Monitors console errors and checks for error elements on the page after
 * making changes to settings. This helps identify validation errors or
 * save failures.
 *
 * What this tests:
 * - Console error detection during setting changes
 * - Network error monitoring (4xx/5xx responses)
 * - DOM error element detection (.error, .alert-danger, etc.)
 * - Setting input interaction (dropdowns, text fields)
 *
 * Prerequisites: Web server running on http://127.0.0.1:5000
 *
 * Usage: node tests/ui_tests/test_settings_errors.js
