feat: add i18n support for backend API and Telegram bot (#797)

* feat: add i18n support for backend API and Telegram bot

- Add comprehensive i18n support for all backend API error messages (zh/en)
- Add /lang command for Telegram bot to set language preference
- Add bilingual command descriptions for Telegram bot
- Support per-user language preference stored in KV
- Global push uses DEFAULT_LANG, user push uses saved preference
