Add Persian (fa) localization and an in-app language picker (#1443)

* Add Persian (fa) localization and an in-app language picker Persian was the one notable gap in the 29-language catalog. Translate all 381 strings (plus the share extension) with proper plural substitutions, and register fa in knownRegions. Settings gains a LANGUAGE section: a picker over every language the bundle ships (native names via Locale), backed by an AppleLanguages override so users can run bitchat in a language different from the device's. Localization resolves at process start, so the picker surfaces a restart note. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Remove unused AppLanguageSettings.currentOverride (Periphery) AppInfoView reads the override via @AppStorage, so the accessor was dead code and failed the Periphery CI scan.
