Add cospendI18n.ts with 100+ translation keys covering all pages, components, categories, frequency descriptions, and error messages. Translate BarChart legend, ImageUpload, UsersList, SplitMethodSelector, DebtBreakdown, EnhancedBalance, and PaymentModal. Update LanguageSelector and hooks.server.ts for /expenses.
