feat(i18n): add internationalization for all create pages

Implemented i18n across all three create pages with translations for 7 languages (en, de, ja, hi, es, la, goh): - Created comprehensive translation files in src/i18n/locales/create/ - Updated /create (hub) page with all card content translations - Updated /create/abacus page with parameter labels and help text - Updated /create/flashcards page with UI elements and status messages - Integrated create translations into main messages system Translation coverage includes: - Page titles and subtitles - Feature descriptions and lists - Form labels and placeholders - Button text (normal and loading states) - Error messages - Help text and instructions 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
