Closes #11199 # Which Problems Are Solved This PR refactors the login app to load allowed languages and the default language directly from the Zitadel API equivalents (`getGeneralSettings`), rather than relying on a hardcoded list. This ensures that the available languages in the UI and the locale selection logic match the instance's configuration. # How the Problems Are Solved - Fetches allowed languages server-side and passes them to the LanguageSwitcher - The NEXT_LOCALE cookie and Accept-Language headers are now strictly validated against the API-provided allowed languages. - Fallback: If a cookie requests an unsupported language, the system now falls back to the API's defaultLanguage (instead of valid but unconfigured defaults). # Additional Changes Helper: Added `getLanguage(code)` to map API language codes to display names (utilizing Intl.DisplayNames if the code isn't in our static mapping). --------- Co-authored-by: Livio Spring <[email protected]>
