TypeScript + React componentization; camelCase for frontend-backend interfaces

Backend: import_api_keys_batch(keys) (fields: name, keyValue, platform, description)

1. Create new language file in src/i18n/languages/ (e.g., de-DE.ts)
2. Reference existing format and translate all text
3. Register new language in src/i18n/index.ts
4. Add translation in public/preview-i18n.js
5. Add window title translation in get_preview_window_title function

• Preview window uses independent i18n system (preview-i18n.js)
• Supports data-i18n attribute for translatable elements
• Window titles set dynamically via backend commands

• Define COLUMN_HEADERS mapping in src/services/excelService.ts
• System auto-detects current language and matches headers
• Intelligent fallback to default language when match fails

API Key Manager supports 9 languages:

• Select desired language in settings panel
• Interface updates immediately to selected language
• Independent preview window syncs language
• Excel import matches headers based on current language
