- Updated docker-compose.yml to include environment variables and health checks for the app service.
- Modified Dockerfile to install curl for health checks and adjusted the build process for backend services.
- Improved user notification handling in activation, blocking, and config revocation commands by integrating Telegram notifications.
- Added new test cases to validate the updated command handlers and Telegram notifier functionality.
- Enhanced documentation to reflect the new Telegram bot features and user management improvements.
