- Brand-analyzer prompt now lists every supported language instead of only
en/pt-BR/es, so onboarding autofill can detect the 12 added languages. The
backtick-formatted list is built in BrandAnalyzer::instructions(), keeping the
Blade clean and the enum free of prompt presentation.
- Translate the delete-confirmation keyword for el/ja/zh/ar (the four locales
that still shipped the English "delete").
- Make the language and font comboboxes RTL-correct (logical ms-* instead of
physical ml-*), and let the language combobox be searched by English name via
a visually-hidden label (ContentLanguage::options() now exposes englishName).
- Correct the ContentLanguage class docblock: the enum is also the source of
truth for the UI locales' text direction.
Tests: SetLocale middleware dir/RTL, isRtl and the full 15-language
englishName/label match arms, LLM language detection beyond en/es/pt-BR, and
store-path persistence of a non-default content language plus rejection of an
unsupported one.
