🤖 Android

• AzifaceMobileModule.setupI18n() now creates localized resources with createConfigurationContext instead of mutating the app/base context configuration with updateConfiguration.
• DynamicStrings accepts a Resources instance (setResources) and, on build(), fills every null string with the localized value before calling FaceTecSDK.setDynamicStrings().
• Localization.getLocale() now returns a java.util.Locale (Locale.forLanguageTag), and pt-BR is mapped to pt-BR (resolves values-pt-rBR) instead of pt.
• Removed unused imports (DisplayMetrics, Locale) from AzifaceMobileModule.

🍎 iOS

🧪 Testing Notes

1. Set the device language to a language different from the one being tested (e.g., English).
2. In the example app, call setLocale('es') (or any other supported locale, including pt-BR).
3. Start a session (liveness, enroll, authenticate, photoIDMatch, or photoIDScanOnly) and check that every FaceTec screen is shown in the selected language.
4. Call setDynamicStrings with a partial set of strings and check that the customized strings are shown, while the remaining ones follow the selected locale.
5. Call resetDynamicStrings / setLocale('default') and check that the SDK goes back to the default strings (English).

• Tested on Android (device/emulator)
• Tested on iOS (simulator/device)
• Automated tests added/updated
• QA passed
