Adds Asturianu, translated in full (345 strings), plus the wiring to make a minority language work end to end — the OS language picker is an unreliable way to reach it, so the in-app choice must be explicit and remembered. - Model Asturian as the real `ast` locale (honest, international-by-design), not a fake `es-AST` region — slang rejects a 3-letter region anyway. - Flutter ships no Material/Cupertino/intl localizations for `ast`, so map the framework chrome to Spanish (`materialLocaleFor`); the app's own text stays Asturian via slang. Fixes an "Invalid locale ast" crash when the auto-backup date was formatted with intl. - Persist the picked language in the keystore (LocaleStore) and restore it at startup so it survives restarts and wins over the device locale. - Settings: add the Asturianu tile; compare the full AppLocale so `es` and `ast` aren't both marked selected. Tests: LocaleStore round-trip, locale switch + Spanish-chrome fallback, and a regression for the intl date crash under Asturian.
