feat(i18n): add Portuguese, Finnish, Polish, Russian, Arabic, Japanese

Extend FURNIDATA_LANGUAGES from 8 to 13 (nl/en/de/fr/es/tr/it/pt plus
fi/pl/ru/ar/ja). Official Habbo translations for fi (habbo.fi),
pt (habbo.com.br) use hotel gamedata; pl/ru/ar/ja fall back to
LibreTranslate en->xx. Docker LibreTranslate now loads 13 language
models (en,nl,de,fr,es,tr,it,pt,fi,pl,ru,ar,ja).
