Enhance configuration and logging for user management commands

- Updated `.env.example` to include new settings for trusted proxies and networks for better security with X-Forwarded headers.
- Modified `BlockUserCommandHandler` and `UnblockUserCommandHandler` to include logging for gateway update failures, ensuring better traceability of issues during user blocking/unblocking.
- Adjusted tests for command handlers to incorporate logging functionality, improving test coverage and reliability.
- Updated frontend configuration to dynamically set the server port based on environment variables.
