LOCALES is now built via Object.fromEntries from SUPPORTED_LANGUAGES,
so adding a new language only requires one change in supportedLanguages.ts.
Also types translations as Record<SupportedLanguageCode, ...> so TypeScript
enforces that every supported language has a translation entry.
Move language list to supportedLanguages.ts so TranslationContext and
settingsStore can import from a single source of truth, eliminating
the hardcoded array in setLanguageTransient.
- Use apiClient instead of raw fetch() in configApi.getPublicConfig
- Validate DEFAULT_LANGUAGE against supported codes on server startup
- Log warning instead of silently swallowing fetch errors in LoginPage
- Case-insensitive browser language matching in detectBrowserLanguage
- Guard against undefined navigator in detectBrowserLanguage
- Validate language code in setLanguageTransient before applying
- Import directly from TranslationContext instead of barrel index
Replace the language cycling button on the login page with a dropdown
showing all 14 supported languages. Add automatic browser/OS language
detection via navigator.languages, falling back to a configurable
DEFAULT_LANGUAGE env var, then 'en' as last resort.

Add Arabic to the client i18n system, expose it in the language selectors, and enable RTL document handling. Also localize the remaining language-specific UI bits used by the login, demo, Vacay, and GitHub panels.
