- Set default API port to 18080 in config.py - Add configurable validation_targets to SettingsSchema and DEFAULT_SETTINGS - Update ValidatorService to support runtime test URL updates - Hot-reload validation_targets from DB on startup and on settings save - Add domestic fallback URLs (baidu.com, qq.com) to reduce foreign dependency risk - Update Settings.vue to allow adding/removing validator target URLs in UI
