fix(i18n+settings): rename pt-BR→pt, fix theme/locale persistence

Root cause: user_settings table was missing theme, locale, font_family,
font_size columns — PocketBase silently dropped them on every save.
Added the four columns via PocketBase API.

Also:
- listOne now sorts by -updated so the most-recent settings record wins
- PARAGLIDE_LOCALE cookie is now cleared when switching back to English
- pt-BR renamed to pt throughout (messages, inlang settings, validLocales)
