Introduce a dynamic SOCKS port feature: add PREF_DYNAMIC_SOCKS_PORT key, settings UI checkbox and localized strings, and pref XML entry. SettingsManager now holds a runtimeSocksPort, can generate and refresh a random port (generateRandomSocksPort, refreshRuntimeSocksPort) and respects the dynamic setting when returning getSocksPort(). V2Ray service startup triggers a runtime port refresh. Settings UI disables manual SOCKS port input when dynamic mode is enabled. Minor i18n additions (QR code/title) included for several locales.
