The profile and device settings language dropdowns (preferred subtitle language, spoken language, metadata language, device audio language, and per-library audio/subtitle overrides) were built from two hardcoded 12-language lists, so Dutch and 24 other languages supported by the canonical list in languageNames.ts could not be selected and stored codes like "nl" rendered as raw codes instead of names. Derive both settings option lists from the shared LANGUAGES array and route getLanguageLabel through getLanguageName, so every supported language is selectable everywhere and stored values always render a proper display name (e.g. "nl" -> "Dutch"). Options are now alphabetized by label, matching the other language dropdowns that already use LANGUAGES; the "No preference" sentinel stays first.
