Merge main branch i18n enhancements while preserving Electron architecture

Core merge strategy:
- PRESERVE all Electron functionality including desktop/mobile switching
- PRESERVE enhanced i18n translations (electron has more complete translations)
- PRESERVE Electron directory structure (src/ui/Desktop/*)
- PRESERVE version 1.6.0 and Electron build scripts
- KEEP mobile keyboard and cross-platform support

Key decisions made:
- Chinese translations: Keep electron's 854 lines (vs main's 776 lines)
- English translations: Keep electron's enhanced translations
- UI Components: Keep Electron's Desktop/* structure intact
- Package.json: Keep version 1.6.0 and all Electron dependencies
- i18n config: Keep electron's './locales/...' path for Electron compatibility

Result: Successfully merged i18n improvements while maintaining full Electron + mobile support architecture.
