- Introduced a new i18n module for managing translations and language normalization, supporting both Russian and English. - Updated various handlers and services to utilize the new translation functions for user-facing messages, improving user experience based on language preferences. - Enhanced error handling and response messages to be language-aware, ensuring appropriate feedback is provided to users in their preferred language. - Added tests for the i18n module to validate language detection and translation functionality. - Updated the example environment file to include a default language configuration.
