Lazy load translations and date-fns, server side support for "Browser Default" language (#2380)
* Lazy load i18n translations. * Lazy load date-fns * Fix inconsistent DOMContentLoaded event. Only when no translations and date-fns have to be dynamically loaded (e.g. for en-US) the NavBar `componentDidMount` is early enough to listen for "DOMContentLoaded". Removes one redundant `requestNotificationPermission()` call. * Rename interface language code "pt_BR" to "pt-BR". Browsers ask for "pt-BR", but the "interface_language" saved in the settings dialog asks for "pt_BR". This change will make the settings dialog ask for "pt-BR" instead of "pt_BR". For users that already (or still) have "pt_BR" configured, "pt-BR" will be used, but the settings dialog will present it as unspecified. * Use Accept-Language request header * Prefetch translation and date-fns --------- Co-authored-by: SleeplessOne1917 <28871516+SleeplessOne1917@users.noreply.github.com>
